I have no battery power in my Scamp. Plugged in to shore power everything works. As soon as I unplug nothing works. I took out the battery and charged it so it reads 12.8 volts. Still nothing works. I replaced the fuse on the battery cables and checked the fuse under the front bunk. I did have a new inverter installed along with a new air conditioner this spring at Backus. I know enough about wiring to make me dangerous. Any suggestions of where I can look next would be greatly appreciated!
