When I turn on the main breaker and enter the start code on the key pad, then turn it off and shut off the breaker, there is a fast clicking noise coming from the back of the motor that almost sounds like a spark plug firing or a transducer. If I disconnect the battery cable, the noise stops. I can reconnect the battery and no clicking noise until I enter the start code again. I think there is a relay sticking somewhere. Any suggestions? Thanks
