I'm getting ready to go camping this weekend and went to check my LP level. So I went to the panel where the levels for LP, grey water, black water and battery voltage may be checked. When I pressed the LP button no reading. Then I noticed no readings for any thing. (I'm gonna take a step back here. When I first bought the coach about a year ago I posted a question about turning the batteries off. If I hit on the main and auxillary batteries they will not turn off. I have never been able to turn them off. Thet stay on all the time) Now back to my current situation. The auxillary battery is on (the red indicator light is on). The main battery is off. No red light comes on when you switch it . The voltage on the auxillary battery is over 13.xx and there is no reading for the main battery (blank digital screen-not even a 00.0) Aslo the coach is plugged into 30 amp service right now so regardless of main battery power I would think the LP, Black water and grey water panel indicator lights should work and function. So what could this be. I initially thought dead main battery so I went looking for the batteries. Not in the same place as my previous Pace Arrow. Currently I have a 2003 Pace Arrow. There is a battery under the hood and I found another battery inder the steps inside the coach (actually the one under the steps is two 6 volt batteries linked together). My first question is should there be another battery- the main one. I would think that the battery under the hood is not the main or auxillary. Am I correct. When checking it has plenty of juice. The battery under the stairs also has plenty of juice. Also the coach starts no problem. What else could I check. Could it be a fuse for the indicator panel. I could find a fuse labeled for it. Sorry this is so long. Not an easy thing to explain.
