I have a 2003 Holiday Rambler coach with 12 volt problems. I did not check the water in the batteries, so the went almost dry. I filled them, charged them and all was okay. Today I went into the coach, no lights, nothing on the panel that shows fuel level. I cranked the generator and did not show any voltage on the panel. The slide outs work, but nothing else using 12 volts. I had a battery checked today and it checked ok. Now for my questions.
1. Is it possible that one of the batteries I did not check could be bad.
2. Can you disconnect the batteries, and hook up a battery charger to
the positive and negative leads going through the disconnect and
see if the power comes on in the coach, without harming anything.
I have a 2,10,50 amp charger.
Thanks for any help.

I forgot to say I checked all 12 volt fuses I could find in and out of the coach.

Hi Justdoc,
This question might get the best responses if posted in the Monaco Owners forum. One needs to know how the slides are powered and where the generator gets its power from to start. These may be unique to how HRs are built. The Monaco Owner's Forum is at http://www.irv2.com/forums/f115/

just had similar problem with my 2003 Endeavor on Saturday as it turns out it is caused by a bad battery disconnect solenoid switch. Mine is located in the left front compartment inside the plastic box that houses all the chassis fuses
Hope this helps as I just ordered the replacement and should be here tomorrow

to test that solenoid there will be two big terminals and two small terminals , On the small terminal Neg side it should be purple wire use a jumper wire from that post to frame and if wire arcs or gets hot the solenoid is bad. U can do a simple test and check the lights on the interior by attaching a wire from Neg side to positive side to the larger terminals if lights do come on replace the solenoid

Extreme:
Thanks for the info. I changed the 4 batteries. I have lights. So one or more batteries must have been bad. I looked for the solenoid you described and found it in the first bay in the front under the drivers side.
I located the solenoid and called a friend who works on Holiday Ramblers and he told me that the solenoid in that box is for tying the 2 sets of batteries together if the chassis batteries are weak. He said he just was not positive if that would work the inside lights. He will check that for me. However on the solenoid I have a 5 amp, 32 volt fuse that is fried. Please let me know if that new solenoid solves your problem. Good luck and thanks again for the info.
