Fuse blows

MarkS

I changed batteries to a deep cycle lead acid.on T@G. When I turned on battery the 20 volt fuse repeatedly blew as soon as I turned on the battery. I have no idea what circuits are connected to that fuse. All the 12 volt items (lights, pump, fridge, stereo, tv, disc player) all seem to work when hooked to shore power, and I put in a 30 amp fuse to test and that also blew. Anyone have any idea what could be the issue?

The 12 volt items work on shore power as they are being fed by the onboard converter which is knocking down the 110 volt supply to 12 volts. I would first check and verify that you are hooking up the positive and negative cables to the correct terminals on the new battery. I would NOT suggest bumping up the fuse, it's blowing for a reason.
