Car Forum / Driving, Maintenance, Tuning / RVs / March 2007When running the Gen, will it charge up the engines battery as well ?
Just curious to know if when running the Generator to charge up my Coach Battery, if it will also charge up my Engine Battery too ? (i do have an isolator control in the engine bay). And...which will charge the Coach Battery faster : Running the engine at idle or running the 2.8 kw Generator ? Thanks much.

It all depends on how it is wired. A fast and easy way to check is to check the voltage of the engine battery with the motor not running, then run the generator and check the voltage in your engine battery again. If it increases, then it is charging your engine battery. I doubt either the engine or the generator will charge your battery any different. Usually the battery will only take what charge it needs up to the voltage being supplied. Both should produce approx. the same voltage.

Nope! >>Just curious to know if when running the Generator to charge up my Coach >>Battery, if it will also charge up my Engine Battery too ? >Nope! Yep! That is, if your rig has a solenoid connecting the two batteries when the ignition is in either the ON or the ACC position, as mine does. Switching the ignition to ACC while running the generator or plugged into shore power most definitely *does* charge my engine battery.

May be the wrong answer. It depends on the motorhome. I have a 2000 Bounder and both house and chassis batteries are charged either from shore power or generator. This was not true with earlier model Bounders. I believe the change occurred in the 95 or 96 models. Don in Tracy, Calif. >> Nope! > >May be the wrong answer. It depends on the motorhome.

I >believe the change occurred in the 95 or 96 models. As I mentioned, my '95 Class B is that way. I bought it used in '98, but I believe the solenoid was in there as original equipment. I have since replaced the solenoid with another one like it because the original stopped working -- the ground connector was badly corroded. I can't imagine why anybody would NOT want this arrangement in a MH. If one doesn't have it, it's a piece of cake to add it. GB in NC |
