Thanks for all your help guys, it turns out the the pressure in the fridges system was unbalanced so turning all the electric off for 10mins reset it and now the fridge is working like a dream
thanks especially for the tip on keeping the revs up while charging, it’s the first time we have ever charged while stationary we haven’t really stopped anywhere longer than a day before so have always charged while on the move.
The engine had just been started when the picture was taken so hadn’t had time to heat up, was just to show what were working with. Anyways thanks for the suggestions were still getting to know her so any advice is all good
