Ok - I admit it, the weather and general laziness has left me with batteries not strong enough to start my motorhome. It has been extremely cold!!! Now what do I do to jump it or somehow charge the batteries enough to start it? I am new to this and know I sound clueless.Thanks for any help!__________________________________________________________________DandDClydes - 2014 Newmar Ventana LE 3845 - Pennsylvania arctic

I can I believe. Does the start battery for the coach also start the generator?

generator on my 02 Fleetwood gets it's juice from the coach battery . . . . I think. Many Class A's have a push switch on the dash connecting coach and chassis batteries together. That jump started mine for a month while I shopped around for a new chassis battery. If you're going to be wheels up for month+ you might invest in a battery tender. Make sure what you get says it will MAINTAIN a battery. It doesn't have to be big to maintain. Battery Tender is a brand that made these pretty popular. I'm not sure FLOAT and MAINTAIN are the same thing. Best,- bob

If the house batteries have a good charge, hold your boost switch on for a minute or so and then try to start the engine.Or, you could run a jumper cable from the house battery positive connecter to the chassis battery positive connector to jump start the engine.Either way you are doing the same thing.

Hi,Are you in a diesel or a gas RV? More information is needed.If you have a block heater, plug it in for at least three hours before attempting to start. While that is running put a battery charger on the starter batteries.To prevent this from happening again add a Trik-l-Start, or an Amp-l-Start unit between the "house" batteries and the chassis battery bank.
