Nicki Posted November 23, 2008 Report Share Posted November 23, 2008 Is the light still the same colour as the other one or has it gone a slightly pinky colour? Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted November 23, 2008 Report Share Posted November 23, 2008 If you blew the 30Amp then you have got a wire going to ground and shorting out.Take the plug off the back of the light unit and check each pin with a multimeter between it and the negative terminal of the battery. Then without the power on, switch on the full beam, and check which ones go to ground then, Your find out which wire is shorting out then, and can trace it to find your problem.John Quote Link to comment Share on other sites More sharing options...

Lee_ Posted November 23, 2008 Report Share Posted November 23, 2008 Remember the fault could also lie within the wiring to one of the halogen spot lights or the xenon. Quote Link to comment Share on other sites More sharing options...
