You will need to consult the EVTM to determine what circuits and wires might be causing this.
Troubleshooting a short circuit in a car is among the more challenging projects. Be prepared to cut and splice wires, remove panels, open wiring harnesses, and generally get frustrated. Either get plenty of spare fuses or put in a resettable circuit breaker for live testing.
Otherwise, get a digital multimeter with a audible continuity beeper. That will help alot by letting you connect the meter with clips and then listening for the indication of the short. Unplug, if possible, load circuits. Cut wires only if needed. Once you identify the branch of the circuit that has the short, you will need to disconnect loads from it until you locate either a shorted load or the individual wire that is shorted to ground.
Good luck. This is a time consuming project unless you get lucky and hit the problem quickly.
