A loose or corroded ground connection often causes trouble. Trace power from 7 pin back into trailer wiring.
The 30amp circuit breaker is good, good connection, and Cleaned it up.
Trailer charges the two Batteries great plugged into 120vAC.
Power from truck pig tail is 14.5VDC to breaker/fuse box, But is does not go to the batteries.
The trailer must not have the battery charging from the truck, only from 120vAC.
Too late To spend any more time on this, Soon as the rain stops Sunday We are Rolling out on the road trip.
I have a generator for any spot along the road, and Full hook ups at rv stops, both with 120vAC to keep the batteries charged up
Thanks For the input, Breaker 19, Breaker 19, Trucking over and out.
