Chassis Battery Charging

[davidbrady]

Chuck,

I'm going to backpedal on the two lead single bank 24V charger idea. I think you're better off with a charger that provides two banks of charging like the Guest 16202. Gil Johnson just informed me that when the ignition key is in the off position the chassis battery Vanner Equalizer is turned off. This means that charging 12V batteries in series with a single 24V charger may result in unbalanced charge and possibly gassing of one of the batteries. To avoid this problem we had better stick with the tried and true two 12V bank charges wired as Vantare has done in my schematic. I posted links to my schematics on WaGu. Marathon has chosen this approach in their later coaches for probably the same reason.
