12v not working on my thetford n180
I have a fiat ducato based autotrail cheyenne 660se 2007 and the thetford n180 fridge is not working when on 12v (van running). I have replaced the fridge PCB and the 12v heater element, plus the fridge works in 240v and gas. When I put the fridge in battery mode (ie charged form the van) the 12v switch relay on the fridge pcb clicks on and off and affects the whole van, for example the aircon light flashes on and off in time with the pcb relay, the engine slightly revs up and down and the fridge light flashed in time as well. I think it is a dead short at some point but there are no issues that I can see. I believe somewhere in the van there is a fridge power relay, but I can not find it. Any ideas guys.......
