battery charging (I mean draining)

[lundy]

I sure would like to know what steps to take to keep my chassis batteries charged. It has been to dealers without success. If I fail to disconnect the chassis switch, they go dead within 3 or 4 days; so much so that the booster won't kick in. I must use a jumper. It gets a little discouraging driving a $300K motor home that has to be 'wound up' all of the time. A fast idle does nothing after starting. The transfer switch has been replaced, the inverter in the gen has been replaced and have blown the main 250 amp fuse. I am getting ready to head north and had to use a charger (again) to get enough power to start. It is an '06 and the dealers and factory have not been very helpful to isolate the power drain. This plus $3 a gallon is causing me to wonder where all the fun is!!

Lundy,

sorry I'm not familiar with the Alpine electrical sys. Most class A coaches have an "Aux start" rocker switch in the drivers cockpit dash area, for when the chassis batteries are dead , you hold that switch down and it lets you start using the house batteries.
Until the experts figure out your problem, here is a quick, simple and cheap way to bypass your current problem, as long as your house batteries are being recharged properly.Trik-L-Start
