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

Good point, i didn't have a replacement fuse so made the jumper for test purposes, but probably not a recommended practice. So i thought it should be fixed, but no such luck. i was able to start to READY, and drive the car, but still getting the same DTCs when trying to chargge. The fan and water pu...

Re: Heat Damaged Charger Plug

i recently had the MCU fuse and OBC snubber caps fail in my 2012, and have made repairs with pictures in the troubleshooting thread. But in thinking back to the events before that occurred, i had been using the OEM Level 1 EVSE to chargge my car for about 2 weeks. Usually i use my Level II Blinnk un...

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

@Harw40 Thanks for the additional details about your OBC failure. We have ideas of the root cause but nothing definite, although lately i have been thinking that the MCU fuse is the weak link in the chain and may be the culprit to initiate all the damage. Other factors such as weak Aux battery, sudd...

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

@fabele Your Aux battery measurements indicate that the 20A fuse in the MCU (under the little cover plate) has blown. It provides a path for power from the main pack to the DCDC converter, which if working then you would read 14.4V Aux during READY. Based upon the experiences reported here, the snub...

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

Howdy Mark and Welcome, Sorry to hear you are having problems with the OBC. It sounds like you have had a failure on both the AC input side, and on the HVDC output side, which is not typical. It may be that more details of your failure would help determine what happened--usually these two don't happ...

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

Howdy Ferenc, and Welcome to the forum. First thing: What is the age and condition of the 12V Aux battery in your car? Is it old, weak or worn out, or the original (7-year old), then replace it and try again. It doesn't hurt to inspect and clean the contacts in the car port and the EVSE handle, also...

Re: Battery Replacement - Lessons Learned

Sorry to hear Suzanne. Where are you located, maybe someone close by can use one of the phone apps (Canion or Hobdrive or the other one) to do an independent check on whether your pack is normal or defective and you are entitled to a new pack under warranty. Or you could buy the dongle for $50 bucks...

Re: No READY. P1A15 error. Condenser charge timeout.

Yes it does go to the bottom of the lower right corner of Lic's photo, to Connector CN4, labelled "VDC". The red and blue wires are from the (+) side of the pack and route to pins 1 and 2; the white wire is from the (-) side of the pack and routes to pin 5. CN4p1 then routes to CN5p1, labe...
