I'll try this again but I appreciate Phil P and CW3 Jason responding to older post.
In Gunnison, Co. last week I was having major loss of battery charge within a few hrs. Found battery in poor condition, bought new one and put it on charger. Now I have zero power to all 12v accessories. All cables correct on battery. Fuse panel has no bad fuses and no breakers in that panel are tripped. All 3 fuses in charger,converter are good. Those wire terminals tight. Still no 12 v power, only 120 power works....about out of ideas so anyone else able to help me keep my sanity! I'll be your "bud" forever.
