No Power for Generator

[overrun]

I recently had the coach batteries replaced with 2 6V ones, and initially I thought everything was OK, till I tried to use the generator. The Generator will not start, and its control panel has no lights, also the starter on the Generator itself does nothing. I have looked thru all of the breakers that I know of, including a check under the bed.

HELP! Not even sure where to look at this point.

Thanks in advance

Not sure if a pair of 6V batteries are correct. I replaced my house batteries in July on a Precept 35S, requires 2 x 12V.

If the 6V batteries are in parallel like my 12V batteries then you won't have enough power to crank the generator starter motor.

does anything else work? is the lighting dim? if so are you sure you have them hooked up correctly? you should have 12v on the + side one battery and the - of the other battery...

also the generator has it's OWN set of cables.. so if you had someone do it did they hook those back up?

Yes Everything else still works with no dimming, even the Inverter. There are two wires to the batteries. Two connecting positive of one and negative of the other.

The two batteries are joined together + to - with a jumper, to make one large 12V, just a lot more amps than before.


Perhaps this may also be helpful, the Bypass switch does not help either. I am wondering if it is something closer to the generator.

There may be a positive or negative that was not reconnected and it feeds the generator.

We changed our two 12 volt coach batteries out this year for two 6 volt from Costco wired in series and everything works just as it should.

It works now! Took another look at the wires, and two lines were on the - terminal, but looking inside its bushing, the line was red. Hooked up the line also to the + terminal and now the generator is working

Thanks for the ideas!
