Motorhome Battery/Electrical Operation 101
I could not find a good You Tube of this, but I am in hopes someone will take the time and explain the Motorhome Battery / Electrical Operations.
There is a Battery Disconnect located in the engine compartment. Instructions say to turn it OFF if being parked for more than 48 hours. I am thinking it is for the Engine Batteries. correct?
When you open the front entry door, most motorhomes I have seen have a "battery on/off" lighted switch" . I am thinking this one is for coach batteries correct? And of course there are other switches like for the entry light, step operation, but my question is this,
Our D/P is garaged, winterized, and I have the disconnect in engine compartment off. Shore power plugged in. Am I putting trickle charge on both sets of battery banks?
I do go out, set everything to normal operation and run everything, every 2-3 weeks. I got to thinking that with that rear engine disconnect set on disconnect or off, is keeping it plugged in doing anything.
When I start the gen set, is it pulling off the engine batteries (Chasis) or the house batteries?
There is also a dash toggle switch near the gen set switch on the dash with a battery symbol on it. I think I read in the owners manual it was for doing something like a jump start from one battery bank to the other. Is that correct? I don't think I have ever used it.
If I have the rear chasis battery switch engaged to ON and say have the DP pulled out and run the Onan for a while, am I putting a charge on all the battery banks? Is this the same driving down the road with the Alternator charging all battery banks?
Lastly, for dependability, longevity and simplicity of your battery banks which kinds of batteries do you recommend going with? The coach batteries should be a deep cycle correct? My battery tray in each will only hold up to 3 batteries in each. I know the chasis bank is always going to be a set of 2 and my house batteries are currently 2 but I could add a 3rd if I wanted to hook it up in parallel e.g. gel, wet, which I may want to consider when adding on some solar.
I know that is a lot to chew on, just trying to grasp a better understanding of how the entire system is integrated with each other.
