Does anyone know if there is a circuit that can be used to tell when the vehicle is actually running? I am trying to wire in a safety mechanism to avoid cranking while the engine is running.

Thanks in advance!

Uh, yeah. The ignition circuits are all live, the alternator is charging, the dash instruments should be indicating various conditions. PLUS there are your ears. Take your pick....

Ignition circuits are all live when the vehicle is not running but key is in on position, so thats not an option.

Alternator charging could be an option if I found some sort of switch that could engage only over 12.6 volts, but I don't know if something like that exists.

Obviously I can't wire my ear into the car.

Thanks!
