hi,Where does the postive feed come from that powers the fridge when driving?I presume theres a relay somewhere,is there just one for the split charge/fridge or is there two?thanks

Not an Autosleeper 'expert' but according to the wiring diagram they are two seperate relays. They are traditionally not a million miles away from the starter battery; usually under the seat, although the split charge relay is sometimes located next to the leisure battery.

Our resident 80-90 Autosleeper guru 'Kevtherev' will be along shortly to either confirm this or point you in the right direction

indeed you need to tell us if you have a leisure batt or not
But generally it will come via a relay, from a battery with the relay being triggered from the alternator.
My relay is easily found in the engine bay
just look at the Alt and follow the thick red wires, there are two attached to the Alt, follow one of them to the relay in the engine bay or under the seat

I have a 1985 Auto sleeper VHT, there is a panel above the sink unit with two switches, a 12volt outlet, the water level guage and a blank panel on it. The first switch is for the water pump and the second is for the fridge. The fridge relay is behind the panel by the water guage. A lead comes via the ignition switch to the fridge switch on the panel and then to terminal 85 on the relay, terminal 86 goes to earth. The main feed for the fridge goes from the main battery via a 15 amp fuse to terminal 12 on the CF9 Zig unit. From terminal 12 it goes through another 15 amp fuse, marked Fridge 15 amp on the front of the Zig, to teminal 11 on the Zig. From terminal 11 it goes to terminal 30 on the relay, through the relay contacts to terminal 87 and then on to the fridge. I have fitted an indicator light in the blank panel to show when the fridge is live. There is also the 3 way switch on the fridge front. I hope this helps, it all depends on what week your van was built and what equipment they had lying around at the time, I have not seen another van like mine with CF9 Zig fitted. I have done a pretty comprehensive wiring diagram of my van if yours is the same I can email it to you.

yes,very helpful,thanks for that Sid,il have a look behind that panel tommorrow,mine hasnt got the zig panel you mentioned,just the standard autosleeper one,so if there is a relay behind there thats where the live feed must come from.Thanks again

Beat me to it
if its not there it might actually be on top of the fridge.
