Thanks, useful information but I am still a little confused. When my toad is in accessory mode the entertainment system screen stays on ( all electronics are functional even through the radio and ac are in off position) I assume this is the cause of the battery drain. Is this the same with you? Otherwise I guess it has to be the charge cable not working.

I tow a 2014 Edge and the manual does not mention disconnecting the negative cable. My question is should I disconnect the negative cable? I have a charge line from the coach to the towed car but the battery still goes dead by the second day of towing.
