Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

I've run the repaired charger now for a few days, and it seems to be stable, so smoke has come out so far ;-) Now that I have a working charger and a test bed, There are a few things I am interested in testing. 1) I've heard several people say that the charger will run even with a DC Voltage applied...

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

So I decided to bit the bullet, and re-install the charger back into the car and test it out. Once I got through fitting it, I turned the key and car went to "READY" with no errors on Dash. I checked the 12v battery and could see it was sitting at 14.4v so it looked like it was charging ok...

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

Hi KIEV:

"The output current is read across R232 which is near the base of the output cap, C115. It looked scorched to me in one of your photos."
The writing on the part looks like BL 00 What value do you think this resistor should be?

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

Coulomb: I like your saying " Endeavor to persevere " reminds me of the Clint Eastwood movie where the old Indian had the piece of red rock candy that was not for eating, it was just for looking at. With all this amount of hours between you and Kenny and myself, don't want to get too anxio...

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

Hi KIEV: While checking over your drawings you just sent, I was looking over the section on the bottom PCB next to CN1 Connector. I spotted a resistor that was a bit diagonal and when I checked from the pin of the IC to the VIA I found it was open. one side was not making contact to the pads. You ca...

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

Maybe the CHGP Signal is like a dead mans switch. If any of the pulses on the input of the 123 are missing, then the CHGP Signal goes away, and the EV-ECU Turns off the OBC Relay 12v supply. That is why I could get the EV-ECU to switch on the OBC RELAY when I connected my ohm meter to the CHGP Pin, ...

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

I did a test, where I connected 240VAC Mains to the terminals on the top pcb, then checked the voltage across the three big electrolytics, same as before, and measured 344.6vdc I then connected the 12v supply to pin 7 of CN101 and measured the voltage across the electrolytics again, and it was still...

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

[EDIT]: Just as I posted this, I just noticed KIEV has just traced out the same CHGP Signal, so my post is a bit redundant. I've just made a discovery by accident. All of the below checking is with charger out of the car. I measured the resistance between the Earth Ground Pin, and the Proximity pin ...

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

I finally got things setup to look at the pins of TR310 on the bottom board with the scope: https://i.imgur.com/bVRRIKV.jpg https://i.imgur.com/IBFgEui.jpg So this looks like TR310 is chopping ok, now I need to pull it apart and find out what test points to test for the other supplies.

Re: Troubleshooting and repair for On-board Charger, DC-DC Converter

Hi KIEV: Yes, my TOP Board appears to be same Version/revision as your picture. Starting with the charger on Bench with nothing else connected, I've made up a cable and I'm supply 13.0v from a motorcycle battery to Pins 12 and 7 of CN101 with ground connected to pin 6. I still have the wires soldere...
