wozzer uk Posted October 10, 2008 Share Posted October 10, 2008 here goes the full dashboard i have taken out to gain access to all the wires. dip beam and main beam not working looked in the haynes manual page 13.15 (dip beam circuit) and i am thinking that the voltage transformer is at fault the light switch is brand new side lights come on ok as does the fog light, the relay behind the dash is working ok as it clicks when i switch the lights on this is a small relay next to the big coloured one but i have no power to the fuses that go to headlights what so ever has any body come across this before....... or any body got any ideas ...... 1987 90 defender with 200tdi fitted wiring loom is from the n/a engine Quote Link to comment Share on other sites More sharing options...
mmgemini Posted October 11, 2008 Share Posted October 11, 2008 Test light. Headlights switched on. One wire from test light to Blue wire from headlight switch. The other wire from test light to earth. Does the test light work ? If no the new switch is faulty. If yes ...Proceed. Headlight switych on. Test light to Blue/Red (dip) wire at dip switch. Does the test light light up. If no, Dip switch is faulty. If yes. Check the Blue/white the same way. Does headlight flash work ? There you go. That should occupy you for all of half an hour. Then answers please. mike Quote Link to comment Share on other sites More sharing options...
