Hello to all repairers. Today I’ll briefly talk about a simple repair of an automatic battery charger “ Orion PW 700» .
When first turned on in the presence of the owner, the unit showed the battery voltage on the dial indicator, the LEDs “Voltage” and “Current” displayed “gibberish” and the charging process was not carried out.
After opening, a radiator with a diode assembly had fallen off the board and a second one with the same assembly was found hanging on one leg side by side. Smiled and delighted.
Initial opening of ROM Orion PW 700
The diode assembly fell off
An external inspection of the board did not reveal anything special, except for swollen power capacitors and sticky liquid underneath them.
Swollen capacitors
To make it convenient to use the board, I removed all the interfering wires.
Bottom view of the electronic board
Two power transistors, after desoldering, turned out to be normal, all other semiconductor elements without desoldering from the board, the short ones, did not show up.
Original transistors are ok
One of the diode assemblies with the legs torn off showed a breakdown, the second was alive.
Broken diode in the first diode assembly
Second serviceable assembly with torn off legs
To be sure, the fireman checked all the electrolytes with an ESR meter, fortunately there weren’t many of them. They were also normal.
And at this time, the fussy owner, at my instigation, with optimism and rapture, scoured electronics friends and workshops in search of conductors and diode assemblies. He brought two new condensers and... a disassembled computer power supply, with the words: “They told you to rip out the diode assemblies from here and, if necessary, transducers, although they are not very suitable.” They said that there was no big difference, these would do for him.” And so it happened, the only difference was in the tension, i.e. the original ones are 100V - and the replacement is 45V. In terms of current, everything matched. Fortunately, the device’s charge does not rise above 14V.
I just had to do a little bit of soldering and testing. I soldered it in, started the device through a 220Vx65W current light bulb, and it worked.
Initial check
I tested it with a load of a 12Vx100W light bulb, it worked like a charm. I tested it on an old battery - the charging current was decreasing and the voltage on the battery was increasing. See photo.
I noticed that the cooling cooler was working a bit slow. I took it apart, cleaned it, lubricated it, reassembled it, checked it was working - everything was good!

Don't be surprised by the photo that the radiators are strangely thin. Thanks to the cooler, the need for monster radiators a priori disappears.
The ROM arrived with some kind of sticky liquid spilled on it in some places, possibly electrolyte.
Leaks under capacitors
I washed the board with alcohol, washed the case under warm running water and soap, dried it, assembled it, started it up, it works, hooked up the battery, tested it, everything works, the charge is on.
The river police did not like our article
Two years ago, Sergei Yakshin went to a corporate party - the company where he worked rented a ship for a trip to Valaam. He never returned, and to this day no one knows where he is or what happened to him. In one of the issues of “Evening Petersburg” we described the history of the search for Sergei, where we mentioned that an incomplete verification of the circumstances of his disappearance was carried out - at least that’s what was written in the decision of the Smolninsky Federal Court. A week later, the editor received a letter from the head of the linear police department for sea and river transport, Alexey Denisov. It sets out its own version of events.
About honor and dignity
Let us recall that Sergei Yakshin got a job at an electrical engineering company in June 2006. A month later, the management organized a corporate trip on the ship “Belinsky” along the route St. Petersburg - Valaam - Mandrogi - St. Petersburg. Together with his colleagues, Sergei climbed on board and went on a trip. When the ship moored off the banks of the Neva four days later, Yakshin was not on board. His mother Valentina Ivanovna went to the police, but they did not initiate a criminal case. The woman first looked for her son herself - on a boat, together with rescuers from the Ministry of Emergency Situations, and then sued the police officers and the transport prosecutor's office. The court agreed that the police and prosecutors did not do a very good job, and decided to carry out a number of additional measures to search for Yakshin and establish the true circumstances of what happened.
In fact, we talked about this in our material: they say that in the first days after the tragedy, the mother tearfully begged the police to organize a search for her son, interview all the crew members and company employees, and involve dog handlers, divers, and Emergency Situations Ministry employees. As a result, several of Sergei’s colleagues and ship crew members were interviewed. Based on the primary materials of the inspection, the transport prosecutor's office issued a decision to refuse to initiate a criminal case.
The letter from the head of the river and sea police began, as usual in such cases: “The information given in the article does not correspond to reality.” Well, this is already understandable - rarely does anyone thank a journalist for writing about any shortcomings. Mr. Denisov has other claims: “It is known how much effort and time is required to create the reputation of an organization, improve its image and the image of a conscientious police officer who takes his direct duties responsibly, in particular. It’s a shame that because of such hastily put together articles, the honor and dignity of the organization and its individual employees are at risk.”
We, of course, do not think that we have damaged the honor and dignity of linear air traffic control in sea and river transport that much. We simply outlined the court decision and reconstructed what happened using documents provided to us by Sergei Yakshin’s relatives. If there is a different opinion, we are always ready to publish it. Not completely (the refutation was sent on three pages), but only the most important, in our opinion, points, while maintaining the author’s style.
Counterarguments
“...On April 23 of this year, in the “Crime” section, an article “How it sank into the water” was published, in which the journalist, who had no idea about the work of the internal affairs bodies in investigating missing people, presented his arguments on this issue. Relying on the emotional story of a mother blinded by grief who lost the most precious thing in life - her son, the journalist apparently forgot that one coin, as a rule, has two sides,” the letter says.
According to Mr. Denisov, the work of police officers is “painstaking and dangerous,” and for police officers from the Department of Internal Affairs on sea and river transport, it is “completely different from the work on land.” It’s hard to argue with this: the department’s service area is really large - 12 ports, 1,772 kilometers, of which 1,362 are on river routes.
“As soon as a message was received from the captain of the ship about the disappearance of a passenger,” the letter quotes the head of the police department at the River Station Kadetov, “an investigative and operational team immediately left for the scene of the incident. Under the leadership of the ship's captain, an inspection of the vessel has already been carried out, and all services have been informed about the incident. At the scene of the incident, our experts carried out the necessary investigations if a passenger disappeared from the ship while it was moving.
It was necessary to establish whether in this case there were signs indicating the possible commission of a crime against Yakshin.” And then Mr. Denisov writes that the police department officers “interviewed the entire crew and passengers who had any information about the missing person and the events of that night.”
Police officers say that they simply did not have the opportunity to launch large-scale search operations, because “the river route, which would have to be explored by divers and employees of the Ministry of Emergency Situations, due to the fact that the place of Yakshin’s possible fall has not been established, is from Mandrog to St. Petersburg - is 150 kilometers."
As for the belated viewing of video recordings of security cameras from the ship (we wrote that they were requested by the police only a month after the tragedy and by that time most of them had been destroyed), then, according to Mr. Denisov, they were viewed in the office of the head of the police department on Rechny Kadetov station, and the search case “has not been sent to the archives at all, as the journalist claims, and the necessary measures to search for the missing man are still underway.”
“We can only hope that after such lampoons,” writes Mr. Denisov, referring to the newspaper publication, “the enthusiasm of our employees will not diminish.”
Data
Having become familiar with the exact opposite opinion, we decided to figure it out: where is the truth? We met with the lawyer of the BMG Public Reception Boris Filimonov, who represented the interests of the mother of the missing Sergei Yakshin in court, and he showed us the documents. The most interesting of them is the decision of the Smolninsky court, on the basis of which the decision to refuse to initiate a criminal case into Yakshin’s disappearance was declared illegal and unfounded.
The court ruled that law enforcement agencies did not identify and interview all the ship's workers, and did not send requests to the regional departments of internal affairs located in the territories that the ship "Belinsky" sailed from 3 o'clock to 10 am on July 24, the night when it disappeared Sergey Yakshin.
The check was considered incomplete, and the court did not rule out the possibility of considering Yakshin’s death a murder, Boris Ivanovich told us. - The police officers probably won’t argue with the court ruling, which has entered into legal force?
As for the operational work of the police department of the Department of Internal Affairs at the MiRT, then, according to Boris Filimonov, they arrived at the scene of the incident in the evening, while the missing person was discovered in the early morning.
At 7:45 a.m., Yakshin’s cabinmate informed his management about his disappearance. A search was organized on the ship, and at 10.25 the cruise director informed the crew of the ship about this. At 11.15, the information finally reached the captain of the ship, who reported it not to law enforcement agencies, but to the general director of the travel company that organized the cruise. In general, police officers arrived on board the ship seven hours after the captain of the ship became aware of the missing passenger. The policemen stayed on the ship for no more than an hour, because by that time all the passengers had long since left for their place of work in Pushkin, and the crew members had gone ashore. On the same day, at approximately 20.30, the motor ship "Belinsky" with other passengers left for another cruise.
Regarding the seizure of CCTV recordings from the captain of the ship: in the case materials there is a request signed by the head of the Department of Internal Affairs at the MiRT - they were requested on August 22, a month after the incident, says Mr. Filimonov.
According to him, one of the ship’s police officers explained that since no one gave him instructions to rewrite the video recording, two weeks after Yakshin disappeared, he copied “the remaining part of the video recording dated July 24, 2006,” which was subsequently presented in police.
Lawyer Boris Filimonov says that the events related to Yakshin’s disappearance, in his opinion, occurred in conditions of obviousness and at the initial stage the crime could have been solved. He believes that the head of the police department at the MiRT, Denisov, simply needed to take a closer look at the inspection materials in the transport prosecutor’s office, in the interdistrict investigative department for transport, or even here, in the editorial office of “Evening Petersburg”. And then, perhaps, he would not have any complaints about the professionalism of journalists, but would have specific questions for completely different people.

Just as every car owner should have a spare tire in their trunk, so every car owner should have a charger in their garage. After all, anything can happen, and sometimes it’s simply impossible to start a modern car, stuffed with electronics, without a charged one. If you have a charger, there is always a risk of its failure. When the electronics fail, you should look for a reliable service where you can repair the charger and starter quickly and efficiently. If everything is more or less clear with gasoline equipment (not for everyone, of course), then with modern electronic devices things are much more complicated. To repair such equipment, you need quite extensive knowledge and, in most cases, special education.
If your charger breaks down, in most cases you cannot repair it yourself. However, for those more knowledgeable, this article will provide some nuances regarding the repair and maintenance of chargers and chargers. To understand possible breakdowns, it is worth giving a list of parts that may fail:
Charging voltage switch;
Diode bridge;
Ammeter;
Capacitors;
Built-in batteries;
Electronic protection against short circuits, overloads, overheating;
Circuit breakers;
Other built-in electronics.
This list of parts may vary, it all depends on the price category of the device. However, the frequency with which the charger is repaired does not depend on the price and category, unless of course we are talking about frankly cheap Chinese crafts. For those who have not even heard some of the words from this list, if the charger is broken, it is strongly recommended not to do the repair yourself. A professional will quickly and accurately diagnose your device. Without the necessary knowledge, you can cause additional damage to electronics, which will negatively affect the final cost of repairs. If you need to repair a charger-starter or just a charger, and the product is still under warranty, then without hesitation, take it to our service center.
It is difficult to give specific advice that would delay the date of contacting the service as much as possible. After all, these devices are protected from short circuits, voltage surges, incorrect + and - connections, battery overcharging, etc. However, you need to look at the instructions to clarify the presence of this or that protection, because it is possible that cheaper models will be deprived of some functions. When using a charger or starter-charger, you need to monitor its performance and not leave it on unnecessarily.
To finally make sure whether your knowledge is enough and whether you can repair the charger yourself, review the following information. Here is just a short list of what you need to know and be able to do:
Voltage measurements;
Ringing circuit elements;
Be able to work with special measuring equipment;
You need to have an understanding of how electronics work;

Engine won't start in cold weather? To avoid this problem, you should use a good jump starter and charger. It will extend the battery life.
Only serviceable starting equipment can charge industrial batteries. Most breakdowns of starting and charging devices are associated with failure to comply with the operating instructions or simple negligence. To restore the functionality of the ROM, it will need to be promptly repaired.
In addition to careless handling, malfunctions can be associated with the failure of worn-out parts. Each working element of the ROM has a certain wear resistance.
Problems with the performance of starter-chargers due to manufacturing defects are much less common. In order to save money, some manufacturers use materials of average quality.
Repairing the ROM should be carried out by specialists with experience in such work. Good knowledge of the design, operating principle, and features of equipment of various brands allows you to make high-quality repairs. The complexity of restoration work depends on the nature of the damage. To determine the cost and duration of repairs, it is necessary to diagnose the ROM.
Common faults
After repairing any starter-charger, a good specialist will give advice regarding the rules for working with the equipment. The reason for most calls to services is ignorance of basic operating requirements. For example, replacing fuses with more powerful ones is strictly prohibited. Many users are not aware of this.
Malfunctions with the starting voltage and charge control unit occur when this structural element is made in the form of enumerating the turns of the switching fork. The contact density is set by the force of the spring mechanism of the adjusting handle. Designs such as “aluminum fork with tire” are subject to rapid burnout.
High-quality repair of starter-chargers involves:
- use of proven materials and spare parts;
- accurate assembly of equipment;
- mandatory post-repair diagnostics.
