P38 Trailer/caravan lights fail

Hi there

when using my P38 to tow the caravan i have a problem that when the lights are switched on, a short while later the trailer lights go out!! Indicators, brake lights work just the side/main lights. If i turn light off and on agian they stay on for about 15 seconds then go out again, and so on. Seems like a relay is overheating with the extra draw of rear lights etc

Any thoughts!!!!

You'll also need to check your wiring
Or only tow in the daylight

There is no relay on the P38 for lighting.
The P38 was designed for towing and the electrics are well capable of coping with the extra lighting loads from a trailer/caravan.
I suggest you check that the negative feed from the car is clean and good for starters. If needs be run a separate neg. to the 12N (Black) trailer socket. If that is good, check all connections in the 12N car socket and also the 12N plug, fitted to the pikey wagon.
I feel that you have a dodgy connection that is breaking down.
