recodiver , If it turns out that you have the Energy Management System and not the Sargent electrical one , then I am afraid that all the information I supplied will not be any help also I do not have any information about the EMS wiring etc. that could help.

It would be however be worth checking any battery/body/module earth connections that you can find.

I think you will find the fuse box near the battery is also linked to the two relays near it and are for starter battery , leisure battery and fridge (the relays are for split charging for the batteries and fridge operation with the engine running.

If you google Sargent electrical Autocruise schematics you should find a wiring diagram for your Motorhome.

It would be worth checking the battery to body and engine to body main earth leads along with leisure battery earth for poor connections.
