raesewell Posted December 28, 2018 Share Posted December 28, 2018 MY first thing to do would be clean the switch with contact cleaner. Quote Link to comment Share on other sites More sharing options...

fastbob Posted December 28, 2018 Share Posted December 28, 2018 So have you actually run a current through both high and low beam filaments in order to determine that this bulb ( lamp ) is " Good " ? Quote Link to comment Share on other sites More sharing options...
raesewell Posted December 28, 2018 Share Posted December 28, 2018 I took the OP at their word when they said bulb was good. Quote Link to comment Share on other sites More sharing options...
Mississippi Bullfrog Posted December 28, 2018 Share Posted December 28, 2018 Check there's no corrosion in the bulb holder. It might be shorting to earth when the bulb is installed. I'd try a spare bulb just in case there's an internal fault with the bulb. I've had bulbs test ok with a multimeter but still play up when installed.

roman emperor Posted December 28, 2018 Author Share Posted December 28, 2018 I have tried new bulb and swapped the dip bulb with high beam (all work) taken switch apart and checked and cleaned all contacts, cleaned lamp holder, put bulb into holder and earthed directly to ground, still no luck, changed relay and no different. ?

Stu Posted December 29, 2018 Share Posted December 29, 2018 It sounds to me like there could be a break in the wire somewhere or a bad connectionThere may be enough strands/connection to show a voltage but not enough to carry the current Quote Link to comment Share on other sites More sharing options...
Bender Posted December 29, 2018 Share Posted December 29, 2018 What voltage do you get on supply to bulb with bulb connected and on, even though it's not illuminated? If it drops voltage trace back and find where you have a good supply, you could try a temp earth feed to see if it's an earth problem Quote Link to comment Share on other sites More sharing options...
Mississippi Bullfrog Posted December 30, 2018 Share Posted December 30, 2018 It sounds to me like there could be a break in the wire somewhere or a bad connectionThere may be enough strands/connection to show a voltage but not enough to carry the current I had this with our old caravan lights. 12v everywhere but nothing worked. Turns out it was corrosion within the cables. They showed voltage but hardly any current was getting through. Quote Link to comment Share on other sites More sharing options...
roman emperor Posted December 31, 2018 Author Share Posted December 31, 2018 Thanks for all the replies, it turns out as stated by Mississippi Bullfrog it is corroded wires that caused the problem, Quote Link to comment Share on other sites More sharing options...
