Part 2, finally edited and uploaded. hope this helps.. also, there could be other failure modes, that this might not fix. https://youtu.be/ynFKclou-LI Thank you to Kiev, Coulomb an Mikedufty for all your help, without you guys we wouldn't have taken on this repair. your expertise and willingness to ...

finally put together a video of starting the repair of the converter.

Merci, j'espère que votre solution va bien.

Excuse my translation, I cannot speak French so used google.

Yes it is great, we are happy. Charged to 100% today and allowed to complete balancing. Then disconnected the 12V and drive battery, left it for a few hours and then filled the hole in the doghouse with neutral cure silicon. Now we have to wait 72 hours for it to fully cure, before I put the top bac...

This morning we have put in the OEM fuse, and put it back on charge. Once we are at 100% SOC, we are going to disconnect the HV and 12V, open the OBC and repot the doghouse with neutral cure silicone.

And for the good news, it looks like ours is fixed, woot! So, what did we do. ⋅ Replaced the two caps with new through the hole caps, however these were soldered to the pins with the two pins that were soldered onto the upriser board used for each leg of the caps (i.e. each leg had the two...

Alrighty, the resistors measured 9.7Ω, which I assume is correct (4.7Ω x 2 = 9.4Ω), so I assume that it good. Here is how I tested it. https://i.imgur.com/JdW1Kyhm.jpg Full image: https://i.imgur.com/JdW1Kyh.jpg We are about to re-assemble the OBC, top up the coolant and run the coolant pump cycle, ...

Ok, relay is good, used bench top power supply set to 4.5V@500mA (@coulomb saw your post after I did the test), heard it click. Woot!

Ok, so about to check the resistors.

I removed the riser board, had to cut it, I managed to save the pins, and soldered the new caps directly to the pins (2 pins per leg), and made sure they were secure. https://i.imgur.com/CJrg4lIm.jpg I am now testing the other components, about to test the semi's in the waffle board and the relay. W...

@skylogger & @coulomb, thanks for the advice, we'll go with the JayCar heat transfer compound, and the natural cure silicone. We got the fuse from Mitsubishi yesterday, I have solar fuses and fuse holders shipping which we should have tomorrow which I will use initially for testing as I do not w...
