Moderator Airhead Posted November 25, 2009 Moderator Share Posted November 25, 2009 sorry the small bulb works the head light dont work the main or pass light works can it be the relay Course it can...but there again it could be another reason, it could even be that the new bulb jou put in is no good! you really need a wiring diagram (usually found in manuals), a multimeter and an understanding of both these things to begin fault-finding properly...otherwise its just buying other bits like a relay and taking pot luck Link to comment Share on other sites More sharing options...

Moderator Airhead Posted November 26, 2009 Moderator Share Posted November 26, 2009 Good to hear its fixed That would have been the first thing I did after the new bulb didnt work ie check the 'new' bulb with the meter. Link to comment Share on other sites More sharing options...

What you did was power the dip beam and main at the same time via the common 'earth' connection. Link to comment Share on other sites More sharing options...
