Here is an update. I read through the manual and it states that if you disconnect the red cable on the battery, it resets the circuit in the front storage compartment that mbopp spoke of. (I guess since you really cannot get to it.) I tried that but the battery is completely shot. I tested the battery which had 0 CCAs where when new it had 500 CCAs. Got 7 years out of it and I guess it doesn't owe me anything since unbeknownst to me, I kept it plugged in when not in use.:S I posted a question on Etrailer about the brake controller and they responded stating that power is getting to the brake magnets and that I should check the red wire from the controller. Also thought about checking the trailer to TV connection as well. Noticed that on the GMs the connector box gives you a schematic on the lid indicating the function of each pin connection.
Thanks again for the replies!
