Of course I mean to close the relay, sorry my fault. I did not bypass the relay. I just measured, if there are 5V at any time there, but the microcontroller seems to stop the charging before opening the relay.

Thank you for alle the help. I just checked a few things like all fuses etc again and some other stuff on the OBC. Here is the summery of all that: The car is not charging, but I get voltage on the orange cables into the OBC. One of the big ceramic resistors was open circuit. I replaced both...

Do you mean the two orange cables going in the top board? I have mains AC going in there, but that was also the case before.

So I checked the waffle plate again and could not find any isseue there. I soldered thin wires to C101 and could read the battery voltage there. All voltages on the caps match the voltages measured by skylogger.

So I was away for a few days and got finally back trying to repair the OBC. I tried to delete the error codes and the car now behaves differently when I plug in the charger. Now absolutely nothing happens, there are no fans spinning at all but the light on the charger turns on for several...

Unfortunately I did not check the waffle plate, but I did not notice any visable damage here. Can you think of anything else to check while the OBC board is in the car or should I remove it again as my next step?

I got my new parts delivered yesterday and soldered them onto the board. I changed the defective resistor, the relay and the snubber caps. I reassembled the OBC and got the exact same problem again. The fans are turning on for a very short time and then the charging stops. I can measure the...

Thank you for your long answer. I removed the waffle plate today, scraped out the potting and desoldered the two resisitors. This was very difficult to do and took me a very long time. The smaller of the two resistors is indeed dead without any obvious sign from the outside. It looks like new...

Sorry for the late reply. I do have continutity between between B and L. I measured the resistors and have indeed an open circuit there. So for my understanding at least one of the resisitors is dead. I would now remove the bottom PCB from the OBC and desolder the waffle plate and scrape out the...

I just checked all fuses and relays in the front, they seem to be fine. My local repair shop already tried to replace the wireing harness without success. I took a look at the board and it looks like new. Is there any way of measureing the resistors without removing the bottom board? I also...

My car is from 2011. I unfortunately do not have a MUT but my dealer said that the car can not connect to the OBC. I am not sure if this is true. I checked the fuse on the right bottom under the cover at the device right next to the OBC. I hope this is the correct one. I can hear three realay...

Hello together, I have the charging problem with my IMIEV. After plugging in the power cable for the 16A charge I can hear a fan spinning for only one second and after about 5 seconds the light on the charger turns off. The cable to the car has been tested and is working. The 20A fuse is fine...
