peacemaker885 Posted September 4, 2015 Share Posted September 4, 2015 Hi guys, I have two questions regarding the house batteries. 1. I need help on determining which wires go to + and to - 2. I'm asking because whenever I plug in the rv into our house ac, one of my 15 amp fuses pop. I disconnected the coach battery and re connected to ac, and the fuse did no pop. So I'm confused. Could it be my wiring? Thank you guys so much for any help. Quote Link to comment Share on other sites More sharing options...
5Toyota Posted September 6, 2015 Share Posted September 6, 2015 if your battery wires have line fuses in the battery box . some do picts would help negative wires have to go on the ground neg post positive wires must be on the positive post.

Bob C Posted September 7, 2015 Share Posted September 7, 2015 Use a continuity tester to find out which of the wires is the ground. That will be your negative wire. Quote Link to comment Share on other sites More sharing options...
peacemaker885 Posted June 7, 2016 Author Share Posted June 7, 2016 Thank you for your responses! I completely forgot that this was way back in September! What ended up happening was the shop completely replacing the electrical panel. Everything works now! Quote Link to comment Share on other sites More sharing options...
