Hi, I've found the rear lights are dim on the caravan and the voltage is only 7.5v. At the car 7 pin socket it is 11.5v engine off (12.5v running) but at the 7 pin plug the voltage has dropped by about 3v which I can't believe is correct. I have replaced both parts of the 7 pin plug and socket but it hasn't made any difference. Does anyone have any thoughts, ideas or suggestions for the voltage drop?
Thanks
Peter
