Hi Don
Nice looking coach.
When I purchased mine in 2006 and got it home, I had severe drains on the batteries. The previous owners had turned the electrical system into a complete nightmare with more after market stuff, bells & whistles, etc. After weeks of trying to understand it I finally literally got so mad I ripped off ALL of the extra stuff and brought the whole under hood electrical back to OEM. Then I started going through the rest of the coach. I think since I've owned it I've ripped out 500 feet of wire, it was an incredible mess.
I now have NO drains on any of the batteries. The last BIG item I found was the electric choke, it was wired direct and not through the ignition switch, so it was on whenever the coach sat.
Here's my recommendations:
1. Very first thing to do, install battery quick disconnects. These are what I installed, fairly inexpensive. http://www.summitracing.com/parts/PCO-5575PT
2. With those, whenever I was not using the coach, I just disconnected all batteries.
3. Starting going through ever circuit and eventually you'll find all of the issues and problems.
4. Inexpensive meters are available that you can clamp over the battery line that tell if there is a draw or not.

Subject: [GMCnet] Hmn (mystery)drain on power system?
When i bought it i had it inspected and told it had a slight drain
that wouldent effect the batterys.the last few months i have been working and trying to get a baseline for how the po had it set up.i have tried to clean any wireing disconnected cbs radios etc.
Still havent been able to isolate it.today i replaced the battery isolater.i read other posts that said they last about 8 years.mine sat for about that long.i had the batterys(house)checked by 3 shops and no one cought they both had dry cells.
I have since filled them and they hold just enough charge but not able to turn over my generator.the batterys are probally that old as well.i have tried to isolate anything that was installed after market to find the problem.
I just havent gotten out a tester and start running the circuits.ive been edcuating myself on whats what and how its connected but so far i am striking out.
Another question is when you hook up an isolater the po had a switch inline a power tap or positive battery post then the isolater.i will post some pictures i am unaware what the switch is for.it has a lot of leads and is tied to tne isolater and the house batterys and the engine battery.i thought this is an odd arrangement.but since i wasent able to deal with the actuall owner i have no clue as to what he did or why.
if needed ill post a photo of the switch.but its inline with the batterys power post(positive) then the actuall isloater is the basic set up?
Thanks for any input?
(btw your off topic lol)
