Compressor Relay doesn't fire???

Invictus,
Before we discuss the original problem, the frame short concerns me. Often a single short doesn't produce the results you are describing. It sounds like you could have another frame short on the robot. Considering the amount of damage you have experienced, there is a good chance the Spike took a hit as well. The LED Mark is asking about is the Relay Tally lights on the DSC. When the DSC is issuing a command to a relay, there is an indicator on the DSC that lights for the relay(s). If one of these is not coming on when you think it should, the relay will never respond.
