Straight box truck with a Spectrum unit on it. When it is

Customer Question

Straight box truck with a Spectrum unit on it. When it is plugged in for electric standby operation, the electric motor comes on for about 30 seconds. The display in the cab says "electric motor starting"...however, it never recognizes that the motor actually kicked on. It comes up with a fault for the electric motor not starting. What tells the controller that the electric motor is on? It doesn't seem to recognize that the motor is working.

The data sticker says " Spectrum TS Gener.". The electric motor runs for 30 seconds and stops. The displayed code is "electric motor failed to start". Does it look for alternator output or something else to indicate the electric motor is operating.
