For some reason the interlock switch that cuts off the ac voltage to the front console TV quit working. Both the TV which is plugged in behind the set and the 120 vac plug that the satellite receiver in the cabinet next to it are dead now even with the engine off and keys out. For some reason, the 120v outlet is marked as a GFI outlet. When the GFI button is reset in the bathroom (it wasn't tripped) all the outlets except the one that controls the receiver are hot.

Has anyone had experience with the interlock and does anyone know for sure where it is located in the Concord coach?

Thanks for the anticipated replies...

Look for any other GFCI or GFI outlets to be tripped. If there are no other outlets check for circuit breakers. If you have an inverter to power this with no shore power or generator, check circuit breaker on inverter. If all above is OK then you will probably have a bad receptacle relay and checking to be sure you have 120 vac feeding it will verify if it is bad or not.

Thanks. No other GFI's, circuit breakers all ok. I guess that I will have to remove the TV and check the outlet behind it. The outlet supplying AC to the satellite receiver must be fed by the TV circuit. I will do the work and report back so that others may benefit from my work. Crazy way to wire a GFI circuit if you ask me.

This circuit relies on a 120 volt relay that is disengaged when the ignition is on, a 12 volt is sent to the relay. Your relay may be bad. On my coach there are 2 outlets located behind the TV and only 1 is disabled with the ignition on.

From the sounds of it the problem is not the interlock but up-stream of the interlock.

usually the interlock only has one outlet, that is the one the TV is pulgged into.. The other outlets in that area are Live full time (Assuming you have an inverter).. So I do not think it's an interlock problem but, assuming you have an inverter, an inverter problem. MOST likely a tripped breaker.
