1992 Monaco Dynasty Dead Battery

[idiocracy]

So after replacing the rear bag and retracting the levelers, I get no crank. Like, the starter isn't even making a clicking noise. Dash volt gauge gets to about 9 volts. What I assume are the house batteries are right behind the passenger rear wheels read 10.3 volts.

Any insight on where the chassis battery is? Or do the house batteries do double duty?

I have the dash apart...its possible that I lost a wire off the starter, but I glanced and didn't see anything obvious.

Any insight will be appreciated.

Forgot to ask, can I charge those batteries to start engine?

All my batts are in trays behind rear pass tire. Originally built , the top tray had two group 31 industrial/farm start batts. Bottom tray was pair of 8D deep cycle.
Previous owner bought 8D starts ....GP31s were dead I moved 8Ds to top tray and used 4 6v golf cart batts as house batts in bottom. I had to cut rear lip that bent inward to fit golf cart batts and remove top tray sheet metal cut out for GP 31s.
There is a combine battery solenoid to jump start MH switch is I left dash panel.

Your batteries are totally dead . Charge them as soon as possible. The voltage may be to low to even get a "click" from the starter.

First, get a jump start to get going. A neighbor may help. Do you have AAA or similar service?

Second, fully charge batteries for 14 to 18 hours. You may need an external portable charger to get voltage up before on-board charger will start working again. Some do. Some don't. Check water level in batteries. Charging consumes water.

Third, get batteries tested. Always store lead acid batteries fully charged. Storing below full will kill batteries.

Fourth, get RV bridge circuit between chassis and house batteries checked. Chassis batteries should not be dead. Only house batteries should be dead.

I think I will consolidate threads...this one thread per topic is getting messy!

I will have to look again, but I thought I saw one large batt on the top tray and one large one on bottom. The trays are a PITA to pull out...gotta love this old stuff!

Yeah, I found the problem. See below.

So this AM I got the thing on a charge. It sat for at least 10 hours, now happily at 14v.

After much wire tracing, some new terminals, a little blood and the random cuss word, I figured out that the rear start panel switch has three positions...Rear...Middle (off)... and FRONT. Wouldn't you know it...when you put the switch on FRONT, she starts right up!

Ahhh crap didn't think to mention the old rear start ...don't feel bad ...owners with way more experience have been had by the rear start panel.
Wouldn't worry about combining just keep them up to date and include the fix.
A single 8D can be ok for a start batt. Even as a house batt if just going where your plugged in. But a pair of gp31 have gone 10yrs or more for many folks for chassis.
The last couple years Sams has put golf cart batts on sale $20 off at end of summer if I remember right.
