Towbar Electrics

Hi Horatio

Many thanks for the information. I thought they were wrong!! However they have now said that when I pick up the caravan, if they are proved wrong and the fridge works on 12V when the engine is NOT running, they will fit a relay (no cost!) If I'm wrong, I'll apologies!!! They say they are going by the instructions issued by Renault for part Modus 2004 on Wiring Kit for 12N & 12S Towing Electrics Part Number:7711-275-704.

The 12S is wired is as follows: Pin1 - Reversing Light (OK): Pin 2 - No power: Pin 3 - Earth: Pin 4 - Permanent supply: Pin 5 - No power: Pin 6 - Permanent supply and Pin 7 - Earth. I do understand from the Caravan manufactuers that there is a relay in the caravan that will take care of the battery charging from Pin 4. Prior to 1997 this did need a car relay and came from Pin 2. Isn't life complicated!!

I look forward to January when I can prove them wrong!!

Thanks for you help
