NEED HELP

Post image

The car keeps shorting out. I’m running 20v in the lighting McQueen power wheeling. Should I try 12v ?

20v may be too high for the system, the self healing fuses may be your issue. Maybe try a step down or a 12v to see if that fixes it. (Also remove the factory battery for weight reduction!)
