Checked 6 volt batteries and they were drained put them on battery charger overnight and replaced, still no power at all. Generator won't start either. Checked all fuses, replaced burnt one on panel under hood for Aux. start. Still nothing. Bought new batteries and installed. Smoke comes out from under fridge when batteries are hooked up. Take cables off batteries. Breaker thrown for front air, leave breaker off and replace cables on batteries. Partial interior lights work now. Start coach engine, try to start generator and melt post on one 6 volt battery. Return battery and get another. Now there are brown singed wires at wiring harness under hood and leading into solenoid in fuse/power box. Now that I feel I have screwed this up enough I come seeking help. What did I do wrong here? Help.
I certainly sounds like you hooked the two new 6v batteries up backwards (or at least WRONG). They need to be hooked up in series (meaning end-to-end) plus to minus to equal 12v from the string. (see photo at end of reply)
I'm not sure what to suggest for recovery at this point. About the best that I can offer is a link to the diagrams
for your Battery Control Center (that black box power/fuse box you mentioned). It does have some trouble shooting procedures in it, in addition to the wiring drawings. (they are NOT point to point schematics.)
If this confuses you, you can at least show it to the electrician/mechanic that you choose to do the diagnosis/repair.
