Just had new tow bar fitted with 13 pin plug and everything works apart for all my tail lights. So plugged my sons car into it but only had 7 pin plug and all my lights worked including tail lights what got a 13 pin tester and it says all lights on caravan work. Plugged it into car socket and it says all them work. Any idea what the fault could be. I’ve also put new 13 pin plug on caravan but no difference
Seems like the typical answer of a fitter, and has been mentioned on many posts of the like on here.
------------- XVI yes?
As well is two words!
How does a sage know everything about everything? or does he? or does he just think he does?
Remember, if you buy something you bought it, not brought it.
I’ve also tested caravan lights out with a supply from battery and they all work. When I took the car back to the fitter I told him that and he said yes because there is more voltage but when you plug it in the car it must have some power returning from caravan plug and 1 off the car tail lights go off
