Thanks Simon! Very good to know he has solved with a new LTC chip.

Re: 12v battery keeps draining - parasitic drain?

One more idea, Are you sure you do not have the ODB Link LX connected?
However 190mA looks too much for it, however it could take active some other car parts.

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

Thanks Kiev, Coulomb and DBMndrake for your valuable comments. Thanks also for the simplified diagram that is very clear for me. So if my understanding is correct, there are 2 theories: Theory N 1, the more favoured, a voltage spike triggers the snubber capacitors and then the fuse blows. Do you thi...

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 ...

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

Can you reach the electrolitics caps terminls? If you have a DMM with capacitor function you may at least test them. It is not a sure test for their full integrity but much better than nothing. I have seen many photos of such board and all of them have these capacitors well suffered the heat, but I ...

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

DBMandrake, I am sorry for your troubles, you were so ansious and then it happened! I think a voltage spike has triggered and brocken the blu snubber cap and then blowing the fuse. Is my thinking possible? I already put 3 SPD 275V AC rated before my EVSE and I am going to put another 3 Varistors at ...

Re: Is my battery dying ?

Thank you very much JoeS for the cell numbering.
I think to swap my weak cells in spring-summer when the temp condition is more favorable and when the other 2 friends of mine will be available.

I will try to add photos following the procudurs in that link.


All the best you too!
Ciao

My second hand C zero of 2011, has only around 24000 km, 14k of them driven by me since I bought it in Oct 201...
