typically, the generator will not charge your chassis battery and it sounds like you charged the house batteries.
(If you charged the chassis battery then stop reading here.)
However most rigs have a "boost" switch that uses your house battery to "boost" or jump the engine battery.
With your generator running and the boost switch held on, you will get the maximum boost.
If your rig does not have the boost switch, run a jumper cable from the positive post of your house battery to the positive post of your chassis battery.
Then start the generator and either charge the chassis battery or jump the chassis battery.

Hi Leo McCloske,
Your going to need one heck of a big booster battery setup to jump start the engine. Not sure if fast or cheap is what you need. If fast is what is needed and you have roadside assistance, call them. You can charge them with a portable battery charger. Consider not putting more than a 20 AMP charger on the batteries. It will take a day or two to get them full. Slow charging batteries is best. A 20 AMP charger is somewhere in the middle of between slow and fast.

Your boost switch on the dash is generally called a MOM switch. It connects the house batteries and chassis batteries together for just this senerio

Mine wouldn't start last Friday-it had been in storage all winter. I used jumper cables from my jeep to the MH chassis battery. Started right up. Got it home and have tested all batteries. All batteries failed testing. Now I am shopping for two new house batteries and a new chassis battery. Our MH was built in Feb 2010 so they lasted five years.

It would be interesting to know if you keep your motor home plugged in while its in storage. If so, your inverter should be keeping your batteries trickled charged during long storage periods. If not then I would suggest starting both your coach and generator periodically when stored. I think this will help prolong your battery life. Just my 2 cents.

Not all coaches the inverter charges the chassis battery when plugged into shore power. My tiffin allegro bus does not do that. I have a seperate trickle charger for the chassis batteries.

When I drove big trucks and they would not start, they hooked jumper battery negative to frame of the truck and then hook positive to the back of the alternator on the large lug. This would by pass the dead battery and allow us to start the rig. It did not do any damage to the ecm.
