Following a recent c/van trip the car switched relay feeding the 12v dc fridge circuit (pin 10 on 13 pin socket) failed so I replaced this with a quality Ryder TF 1170 - 4 relay that worked fine after installation.  However just got back from a short trip
with c/van and the new relay has also stopped working which obviously suggests the problem is with the fridge (Thetford N112) or c/van related circuitery causing some kind of overload on the relay - Anyone else had similar problem or know what night be causing
the relay failure ??  Thanks for any pointers.
