Battery power

[kuba122]

Circuit Breakers at the front just behind the battery on the frame. Check them. Also check the fuses. There is an open somewhere or bad ground. Bad ground "seems" unlikely. I would look for an open on the positive side, first.

Have a 21FBS that I can't seem to run anything off the battery. On shore power or jacked in to tow vehicle, great. Otherwise, nothing. Replaced battery, made no difference. Suggestions?
