have searched the forum but cannot find a thread related to the the TT battery charging circuit breaker/relay. So here is my situation.

When I backed the trailer into the driveway today after getting home form our Thanksgiving trip, before I disconnected anything I heard this 'chirping' sound. I narrowed it down to the circuit breaker between the battery and the rest off the trailer. Obviously the 'chirping' was the CB tripping and resetting. I disconnected the 7 pin plug from my TV and the circuit breaker stopped making a noise.

I know I have some trouble shooting to do but wanted see if anyone has had this issue?

Also, my service engine light on the TV came on just before getting home. Not sure if it is related but seems very coincidental.
