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

Hi Coulomb: Your details regarding extreme situation that can occur across a fuse that is not rated to 450v, probably explains also what is happening with the 2x 1000pf caps in the dog house that are exploding. The caps are across the same high DC voltages in the output circuit that the fuse has to ...

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

Hi KIEV / Coulomb: This second charrger that I am now working on, has all of the symptoms that the first charrger had. The 20 AMP 450V Fuse in the MCU was blown, and the SMD Caps on the vertical pcb in the dog house were blown up. I've de-soldered the verticle pcb and replaced it with two 1000pf 3kv...

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

Just got a phone call from another AEVA Member here in Western Australia that said her charger has also died in here 2010 I-MIEV. Looks like these are dropping like flies. She will be sending me a photo of the top of the charger so I can check the part number and see if its same version as the other...

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

Electropusher: The charger label on your charger has the same Mitsubishi part number 9481A092 as the charger that I just repaired. Both are in 2010 I-MIEVs here in Australia that were built in Japan. You also have the vertical PCB with blown caps in the dog house, VS the older style that had the thr...

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

Hi Electronpusher: <edit> just read your other thread Are you able to determine if the 20 amp fuse is blown that is under the small cover on top of the motor controller box to the left of where the charger is? The fuse contains sand, so you can't just look at it, you have to use an ohm meter to chec...

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...
