Unfortunately there is no 'quick fix' without fault finding.
Purchase yourself a cheap insulation tester/multimeter and then use the principle of 'split by half method' to find your fault. http://www.ebay.co.uk/sch/Insulation-Testers-/121877/i.html Split by half fault finding...... Split half technique is used when fault finding on an electrical circuit. If you have a supply and an earth, you would then check for voltage about half way along the circuit. If you had voltage, you would then pick a point about half way between your present position and earth. You would then repeat with half way of every subsequent half until you had located the fault. Or if you don't have the inclination 'slave' cable(s) in from the relay to the lights until you find the damaged cable. The slaved in cables need only run for diagnostic purposes from a suitable point (relay is favourite) to the light and does not have to be routed in but can be run outside the vehicle until such time as you diagnose the affected cable(s), then replace as necessary. If you go through life with your head in the sand....all people will see is an ar5e!! Treat every day as if it is your last....one day you will be right!! |

Do you have a tow pack fitted ? as the 7/13 pin sockets fill up with water from the back wheels and cause alsorts of problems If everything is under control you are not going fast enough.

Ahhh WD40 on standby then, wash the plug out with it. If everything is under control you are not going fast enough.

The genuine Land Rover part is a sealed unit (filled with some sort of resin), so no chance of water causing this problem.
