We just purchased our most recent Class C, an Entegra Odyssey 24B. Got it home and realized that we had a single Group 24 battery in the stair well. However, a second Group 24 will not fit in the tray due to all of the other electrical hardware in the well.
I usually run with at least two Group 27 deep cycle batteries in the tray, but thatโs not possible without major structural changes. We donโt boondock a lot, but may go out for three or four nights a couple of times a year, so we need some reserve capacity.
I found a large area inside the coach that will allow me to install at least 2 and possibly up to 4 or 5 100- AH lithium batteries. Our converter is Li ready so I donโt have to change that out. I also donโt intend to install an inverter at this time to run AC appliances, just need the DC power for the furnace, frig, pump, interior lights, etc. Spoke to sales/tech person at Li battery dealer they said that in addition to the batteries, I need a battery isolation manager to replace my charge solenoid from the alternator.
I cannot locate the charge solenoid. I found the Battery Disconnect Solenoid, the Auxiliary Start Solenoid and a solenoid on the generator. Itโs on a Ford E450 Chassis. I looked under the coolant reservoir and main chassis control center relay block. I canโt see under the chassis battery, but I stuck my arm down there and took some photos and didnโt see anything. I am looking at the wiring schematics from Jayco and donโt see anything that refers to a charge solenoid. Some people I have ask have said that itโs installed by Ford, others say that it is installed by the coach manufacturer and others say that itโs the auxiliary start solenoid that is used for both charge and start. Any suggestions where to look?
