Truck Battery

I should know this but it has been a long time since I have had any issues - I am connected to shore power but my truck battery is dead. When connected to shore power should my truck battery be charging? My coach batteries are fine.

Unless you have a Trik-L-Start Ultra TRIK-L-START Starting Battery Charger/Maintainer, or something like it, I don't see how your truck battery would charge. So my answer would be no.

It would depend on how your Winnebago is wired. Lots of motorhomes isolate the chassis battery from the house batteries when the rig is parked. I think the idea behind this is that if you use up all of the power in the house batteries, you will not be stranded because you still have a fully charged chassis battery to get you going. I have a 2004 Allegro, and have wired in a small battery maintainer (trickle charger) to maintain the chassis battery when it is parked for long periods of time. The house batteries charge off of the converters built in charger while the coach is plugged in to shore power. You can check with a voltmeter to see if your chassis battery is receiving charging voltage from your converter, by reading the voltage across the battery's terminals while plugged in to shore power.

Yes, they are all different. I'd call the factory with the VIN, they should be able to help.

The Winnies generally do NOT charge the chassis battery from shore power except in the higher end models (mostly the diesel pushers). Install a Trik-L-Start or a Xantrex Echo Charge to overcome this deficiency.
