stupid move

[ADAD437]

ok, i know it was a stupid move but i have issues that are clouding my thinking. i was putting two new 6 volt batteries in for the coach and hooked them up backwards. i now have no 12 volt lighting and cannot crank my generator. any thoughts would be greatly appreciated. so you know i am not always stupid i have a son dying of cancer. much appreciation in advance.

Look at the wiring right near the battery compartment for a fuse.
The inverter may have it's own internal fuse/circuit breaker.

If you actually hooked them up "backwards" most rv's have reverse polarity fuses near the battery or converter. Hopefully just a couple blown fuses.

i failed to say it is a 2005 national dolphin on a w22 workhorse chassis. would you have any idea where that fuse would be and what size it is? i did hook them backwards positive to ground.

What you need to do is disconnect the batteries and hook them up with + to - on both batteries. That will give you 12 volt output.
Right now it appears that you have them connected + to + and - to - which gives you a 6 volt output..

no i have them hooked right, i momentarily hooked positive to ground then i realized what i done.
