Re: Pre charge resistor burned
Solenoid failure is often a cause of this.

Re: Pre charge resistor burned
When the solenoid fails to energize, the controller will attempt to power the motor through the pre-charge resistor. Likely this is what happened. Either the solenoid failed when asked to energize OR the solenoid activation circuit failed.
So 2 possibilities, solenoid failure or solenoid activation failure |
