So with these non OEM fuses, does anyone think it would be doable to convert the fuses without screw terminals into fuses with screw terminals by soldering the fuse to some copper fashioned into screw terminals and soldering the fuse to the copper?

Thanks skylogger, I might get a couple of those, at lest I can test while waiting for the OEM fuse.

Thanks coulomb, just want to source some alternative fuses if the OEM become difficult to obtain. Work on ours starts tomorrow.

Just playing catch up on this thread, haven't had a chance to look at our OBC, and only received the replacement caps on Monday, so I intend to work on it over this weekend. Still waiting on the fuse from Mitsu though. Interesting @skylogger, this could be the cause. When we had the failure...

Hi ChristopheFR, It sounds different because your symptoms are different to the other charger failures, why that is we simply do not know at this point. While I see merit in the Aux Battery theory, I am not completely convinced it is the Aux Battery just yet, since we had our Aux Battery...

Hi Skylogger, I hate it when that happens half way through typing, very frustrating, however I very much appreciate your help and the abbreviated version anyway. We have take out the DC/DC Converter, but I have not begun disassembling it just yet, I will start that this week some time. I...

I cannot collaborate this, as it is only the sellers word, but when we bought the car, he said that he had the Aux Battery replaced because the car would not power up. So the battery is supposed to be about 1 year 4 months old, the battery indicates it is good, but the battery is rather tiny...

Interesting discussion regarding the Aux Battery possibly being to blame for the MCU Fuse/Snubber Caps issue. Taking that into consideration, we have a battery that is rather small compared to the size of the battery box, and hence I would like to swap it out before I put back in repaired...

Make that three, ours has failed exactly the same way, MCU Fuse and Snubber Caps blown.

Well, we finally got our iMiEV home today, so now I can start the work on the repair of the DC/DC Converter. First thing we did was remove the cover from the Motor Controller to check the 450v fuse, got out the multimeter, set it to continuity, placed the probes either side of the fuse, hoping...

Correct, we have to two SMD caps on the riser PCB blown as per your board. We will hopefully have the car moved out to our new house this coming weekend (8/9 and 9/9), we can then start working on our OBC, and inspect the fuses in the MCU and let you all know. Will be replacing the caps with...

if i understand correctly, buying a second hand converter somewhere, and swap it in, should fix the problem? i was told by the dealer that doing that wouldnt work as the converter is VIN locked, though after my experience so far, the dealer appears to be incorrect.

sorry for the late reply, here are some pics, hope these help. also of note, our car is a 2010 model, yet the converter appears to be a 2015, so i am assuming that it is not the original converter. either way, it appears the failure mode is the same as others. these are older...

Gday, we havnt checked the 20 amp fuse on the motor controller yet, but this weekend i will be going to my fathers shop where the car is at the moment, and ill get as many pics and as much info as i can. Thanks again, Rob.

We are after a DC-DC converter, from a salvage i-miev, we are in Sydney Australia. does not matter if it has failed or is VIN locked.

Yes, that clinches it. Now I'm thinking that electronpusher's "resistors" may have been surface mount versions of those Y capacitors. They all look much the same when burned. Is this possible, @electronpusher ? Quite possibly, won't be able to check that for a while though as it is all back...

Yes, it does have DC quick charge, and we are considering borrowing a CTEC CHAdeMO charger from someone here in Sydney, and seeing if we can put charge in that way. We will however still need to charge the 12V battery separately since it currently does not charge from the battery or 240V. This...

Thanks Kiev for all the useful information. It is interesting the different components on your DC/DC Converter compared to ours. We are at this point considering sourcing a DC/DC Converter from somewhere, be that Japan (if compatible) or the UK. However as I suspected, it appears the Japanese...

I am thinking the same thing. The iMiEV does not have a proper EVSE so to speak, it is pretty much a cable that goes from the 240V socket to the DC/DC Converter. Now the iMiEV charge cable lacking the EVSE would dump any surge from the 240V socket into the DC/DC Converter, rather than kill the...

Ok, an update. I think board with the blown resistor has been bonded to the water cooling layer of the DC/DC Converter, it does not appear to want to budge, and I do not want to break it. Possibly it could be attached from underneath, but it does not appear so. We drained the coolant, and then...
