![]() START switch and it would charge the chassis battery as long as one could hold the switch. Or I use the relay to recharge the chassis battery every once in a while from the solar system, when I am parked for a long time. I only turn it on when my solar system is not going to recharge my batteries and I am planning on driving a ways. In my RV, I added a new chassis to coach battery relay near the batteries, and use a switch near the drivers seat to energize that relay. Charging a frozen battery can be dangerous.) (in freezing weather it might drop below 12.2 and a battery can freeze if below 11.5 VDC and below 20F. It should be at 12.8 volts, and stay above 12.6 volts for weeks at a time. Try charging the battery and then disconntecing the negative terminal. Or you might have a internal short in the chassis battery. You can transfer things like the radio memory and car alarms and feed them from the coach batteries, so the chassis battery will not discharge itself. I think you have a new load on the chassis battery, and that is what is causing it to discharge now. Both will cause loss of water, and the typical chassis battery is maintenance free, so you can not add water. It is not a great idea to either let the chassis battery discharge to much, or to leave it at 13.5 volts for prolonged time. I don't think the factory energized this relay on it's own, so you will probably need to add a switch. Energizing this relay will charge your chassis battery if the motorhome is plugged in. You can find the relay by using a pencil (because it is not conductive) and have someone hit the "Emergency Start" from the inside, (sevral times on and off) and listen to and feel what relay is clicking in. I am not sure what relay connects the chassis and coach batteries, but know that there was a big voltage loss across it, so I installed another one with silver contacts (forklift relay). My 97 Bounder has a 12 volt relay under the hood in the box on the driver's side. I use a small smart charger when rig is not in use. Of course, I learn something new every day! Are you sure that it worked that way before, as I didn't think any Fleetwood gasser did that. My Southwind will not charge the CHASSIS battery from shorepower, but WILL charge the HOUSE batteries from the eng. ![]() Most Fleetwood MH products do not use isolators as such they use a relay syetem. You can try locating by having helper disconnect and reconnect battery switches or operate the emergency start button. Most Pace Arrows have a battery control center under the hood on drivers side. "If I can't buy what I need, I'll make it myself." "Don't tell me it can't be done, just tell me it won't be easy." '04 Holiday Rambler Vacationer 36WDD, 2 slides By the way, I have a '96 Pace Arrow Vision, P32 chassis. I have located all of the fuse panels and power centers but don't see anything like what I believe it looks like. It used to so there must be a breakdown in the system somewhere. But the chassis battery does not charge when stored at home between monthly campouts. RV.Net Open Roads Forum: Tech Issues: '96 Pace Arrow battery isolator? Open Roads ForumĬan anybody tell me where the battery isolator is located? My coach batteries charge fine.
