Fellow.netters,
I got a few electrical questions.
Electrical should be fairly easy to figure out.
I try to picture current flowing, as water would.
Which means, it should all be common sense and easy for most.
I STRUGGLE WITH IT.
Background:
I have a coachmen rear bath.
Three new batteries (6 months old) 2 deep cycle (house) and 1 regular for the coach.
I can't remember the cranking amps, but I bought the largest most expensive Interstate batteries I could.
I still have the old "buzz box" as my charging system, and leave it off for most of the time as my motorhome sits in the backyard.
So, that my batteries are not constantly charging, and won't boil the water out of them.
My GMC has been sitting now for two weeks since I got home from Dothan.
I was doing some bulb changing to L.E.D.'s and they seemed dim so I decided to start the engine to see if there was a change in brightness.
When I tried to start the engine it just went click as if the batteries were dead.
I hit the boost switch and there was no change.
My question is:
Why would my chassis battery be dead only after two weeks of sitting ?
I would figure that anything I have run during these past two weeks (radio, 12v roof exhaust fan, etc) would have used up my house batteries, and not drained my chassis battery at all. (P.S. we spend a bit of time in our GMC in the backyard, we just love it)
I had the Mrs., switch the boost switch while I was under the hood and the relay clicks as it is supposed to.
But what I'm thinking is, that maybe things are backwards and that when my boost switch is on normal that it really is on boost and that all three of my batteries are tied together. And, this is why all my batteries are dead.
Does this make sense, or am I not thinking of something ?
Question #2 (or #3)
Is there any way for me to confirm when my batteries are all three tied together (boost switch on) and when my batteries are separated (as normal) two house batteries together and the chassis battery separate (boost switch @ normal)?
Sometimes the obvious seems complicated to me. I guess I ain't too smart, but I am willing to try.
Once I get this figured out, I will have another question about why I can't get my passenger map light to work.
It is also giving me a headache.
I may be over thinking things, and short circuiting my brain matter (whats left of it!).
Thanks in advance for all you all do for me.
Sincerely,
Glenn Gardner
