I have a 300tdi bulkhead and loom fitted to my my '89 110. Last December I had problems with my headlights and replaced the indicator stalk with a genuine Lucas one which solved the problem (Thread).
This morning while driving to work I lost my headlights again and seem to have the same problem back. The position I am in now is:-
headlight switch:
side lights position - work as normal with side lights, tail light and dash illumination working
headlight position - no headlights, no side lights, no tail lights, no dash illumination
Main beam switch:
flash - all working as normal
main beam on - no headlights, no side lights, no tail lights, no dash illumination
I am assuming that because when flash is used the headlights are still fully functioning that the problem is going to be switch/relay/dashboard related rather than a problem with the lights themselves. I have not yet had a chance to take it apart to have a look but if any one can give me any suggestions as to what it is likely to be or specific things to check that would be great.
I am also amusing that it should not be the indicator switch again as that is less than 12 months old, however I will try and test this when I have some time.
If it turns out to be the switch again what causes them to fail? If i have another fault which is causing them to burn out? I would like to rectify root cause rather than just repairing the symptoms.
p.s looking up information on this a lot of people talk about the dim-dip relay. but i have not found a description of what this is is for or how to work out if you have one as my understanding is they were not fitted to all models. Can any one shed any light on this?
