My guess would be something in the modules but I am not sure.
I have also attached a picture of some cables, and would like to know if the one marked with red tape goes to the inverter and the one with blue tape goes to the air compressor for the AC. The cables don't have anything to do with the earlier problem, it's just that Ive made the mistake of unplugging them.
Diagnose the HV-Battery problems with an OBD2 Scanner, gives an rough estimate of the problem. You need someone with a Fisker Karma WDI (Prodis) to pinpoint the exact problem.
Cables (your picture)
Red to the front (red = heat).
Blue down to the electric Air Conditioning compressor (blue = cold).
The “unmark” cable is connected to the Accessory Power Module (APM) (your inverters are located in the rear end)).
By the way, I really hope that you have disconnected the 12-volt battery connector (– Negative, Black) and that the MSD is completely pulled off and stored while you work on the car…
