Do house or chassis batteries start the generator?

Does the generator start off the same battery as the engine or does it use the house batteries?

As written, the answer is yes.

Now for a more useful answer.

I see the first reply mentioned on HIS motor home it was the engine/chassis battery.

On mine it's the house battery.

Makes sense to me...had my house batteries out today...no gen start...soooo must be yhe house side

And what is more a very few rigs have a 3rd (Generator) battery that does the job.

It is all up to the folks who built the beast.


How to figure it out.

Disconnect the NEGATIVE lead from the house battery.

Try to start the generator.

If it starts.. NOT that battery.. IF nothing, re-connect and try again, Varoom on the 2nd try = House battery. (Well the cranking anyway)
