"Trailer Batt Charge" fuse ? and Coach Batt ?

I have had several problems with batteries, and wound up replacing both chassis and coach early last year. During that time I found a blown 30A fuse labled "Trailer Batt Charger" which comes directly off the Chassis Battery terminal. I replaced it and, while checking things last week I found it blown again.

Is this fuse related to the "Coach" batteries or is this related to a "Towed Trailer" ? I did have some wires come loose on the 7 pin plug, which would explain the fuse blowing. I am just making sure I know what that fuse is for.

Welcome rjcunning to the Newmar forum & irv2.
Read this thread about how your batteries should be charged and maintained at their full charged.
The fuse that you have change is must likely as you say for lighting or braking system in tow you may have.
