fridge removal 1989 SMB

I decided to remove the fridge and associated cabinet from my '89 SMB to free up some space. The fridge was hardwired to the 2nd battery. By removing it I have broken the circuit - is there anything simple I can use to reconnect the circuit so that my interior lights and fan will work? Any suggestions would be great.

Re: fridge removal 1989 SMB

Each item should be wired separately to the fuse panel. Are you saying that by disconnecting the wires to the fridge, none of your other electrical appliances work?

I would check the fuse panel for voltage and go back from there, there may be a 40 amp reset able breaker.

Re: fridge removal 1989 SMB

I can't find any breakers. The fuse box appear to be standard ford.
This van has shore power and 12v. All the outlets are wired to shore power. The fridge, water pump, fan and lights all run off the deep cycle battery. They all appear to be wired directly to the battery.

Assuming I am correct, here are my questions:
1. Would removing the fridge break the circuit and prevent charging of the deep cycle battery?
2. Is there any reason I can't just wire up an inverter in place of the fridge? If I do this the deep cycle battery should gradually charge, correct?


Thinking about putting in a xantrex 1000watt pure wine wave inverter for laptop/camera/hard drives

Also FWIW, SMB won't give any advice which I guess is understandable...

If all of the loads were tied back directly to the battery, removing the fridge should not have a impact. What did you do with the wires you removed?

No, you can't add a inverter in place of the fridge, the inverter will only put a charge into the batter if it also has a charger, How do you charge the battery today?

This does not sound like something that sportsmobile wired up, so you are on the correct path looking for Professional help. Better to be save the sorry.

taped the ends, left them in place.

the fridge ran off the 2nd battery which was charged by the alternator. If I wired an inverter in it's place wouldn't it just convert the 12V DC to 110v which could be used to charge laptop/camera, etc? energy source would be the same - the deep cycle battery charged by the alternator...

I am pretty sure they did the work, but would be happy to find someone who can sort this out for me...

Is there always a 2nd fuse box for a 12V system with a 2nd battery? Anywhere else in the vehicle I should look?
