Charge batteries while driving

While you are driving, does your engine charge the house batteries? If not, can you rewire it so it will?

If you do not have the coach batteries disconnected then yes they will be automatically charged by the engine alternator. The chassis battery will have charging priority and once satisfied the coach batteries will be charged simultaneously.

The Georgetown, as with most if not all motorhomes, has a battery control center (BCC) that lets ANY available charging source charge all the batteries, house and starting.

There are current limiters (like fuses), an isolation relay (to prevent a depleted house battery from killing your starting battery), and a battery disconnect switch that can prevent the BCC from doing its job.

This is excellent info. Anyone know if this also applies to coaches with the MBS chassis? If it does, this means my converter or my solar panels are also topping off my chassis battery? Not sure if this is considered a hi-jack of a thread or if related

Since it is a motorhome (Class C) I am sure it has a similar system; but may be wired slightly different and the components may look different.

Thx. I will investigate and verify it applies to my MH. I hope it does. Would take a lot of the worry out of of storage/charging etc. I also have solar topping up my batteries

I called coachmen. Yes their MHs all charge coach batteries off the chassis alternator. However they do not allow the MH charger to charge the chassis battery either via the genny or shore power.

On a Lexington

On a Lexington class B+, which uses same chassis as class C, the generator does charge the house batteries. Can also charge with solar.
