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

Good news. :) The fuse finally arrived today and the rest was a bit of an anti-climax! I fitted the fuse, put the cover back on the MCU, refitted the traction battery safety link, reconnected the 12v battery, plugged the car into charge listening for a bang but all I got was charging. :D I checked ...

Citroen C Zero (iMiev) Repair

Hello all, I am here in need of some help trying to repair this charging board from a 2009 citroen c zero, So far I can see that F701 has blown open and a few of the plastic bases on the smd coils on the top board have melted due to excess heat, also on the main board the 2 ceramic resistors have co...

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

... Also the fuse F701 on the bottom side of the top board is open so that will need replaced too, Does this even seem repairable or am i safer trying an alternative charger? Is there too much damaged here? Would really hate to replace everything then plug it all in for it to all go bang again.... ...

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

The SA should normally measure open circuit, like a capacitor; it is designed to provide a path to ground in the event of a HV lightning pulse. Since the damage was to the ceramic resistors on the AC input side, then it could be that abruptly cutting the AC power with a timer could be the culprit. ...

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

Looking at the pictures, Is the Spark Arrestor (SA) okay? Is the plastic base of coil L705 on the top board melted? i would try to find the same parts online e.g. mouser or digikey, or an electronics parts supplier in Japan if a part is not available from the online sales. i haven't figured out a w...

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

That is a really trashed pair of resistors, and the little one exploded! Those parts are on the AC Input side. i would want to check all the parts on the top board in the AC input circuit also, e.g. lightning arrestor and fuses, plus the AC relay and EMI filter coils and cap. i would suggest to rep...

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

Evening all, I'm here as i'm trying to fix a 2011 Citroen C-Zero which has a problem with this now famous circuit board, First thing i noticed on this is 2 cracked ceramic resistors the smaller 7K one looks a bit worse, apart from that no other visible signs of damage. I've removed all the rubber po...
