Sounds as if you wired the new batteries in series instead of parallel.

check that your batteries are hooked up correctly and that all connections including grounds are clean and tight.

Two six volt batteries SHOULD be wired in series! In parallel you have only 6v instead of the required 12v.

ok , checked the batteries, they are good, but every one says ck the batteries, these are the house batteries that I replaced and not the chassis battries, I thought the insterment gages work off the ignation switch and motor battery and would be seperate from the coach batteries ? am I wrong? I am a little lost thanks for the info............

when shops mess with batteries, they often disconnect both house and starting batteries. sometime the terminals are not cleaned properly prior to reinstallation.

Absolutely!!! I misread the OP. Back to the drawing board. Sorry for the misdirection!

Greenskeeper,

Not sure if this will help or not, but one time when I disconnected my coach battery it took several miles of driving before the computer re-set and the fuel guage reported accurately again. Had me confused for days, but with a little driving it might correct itself.

Good luck!

jhlady you hit the nail on the head, talked to a service manager and that is what his thoughts were, as of now after running the motor for a while the gas gage needle has returned to normal,,,,,,,,,,,,,thanks to all for your input................
