Posting both here and NSXCB.
I run gas discharge xenon ignitors and bulbs on all four headlamps.
Went to use car last night, fully rotated lighting switch; L & R headlamp retractors up, hi[full] and lo[dip] beams on, blue hi beam warning light on.
Pulled turn signal/dimmer switch to go to lo[dip] beam only – nothing –all 4 bulbs still illuminated.
I’m aware that when the main lights are on, both the hi[full] and lo[dip] have a common feed, and that for the lo[dip] position the earth to the hi[full] beam is interrupted.
Today; pulled ‘dimmer’ relay; relay fully operative, [switching coil energized – main [earthing] circuit complete; no power to switching coil – main [earthing] circuit broken]
HOWEVER; with relay removed, [earth to hi[full] beam broken] the hi[full] beam remains on.
Jumping/un-jumping the ‘dimmer’ relay socket – no difference the hi[full] beam remains on.
Pull fuse 52, one side, both bulbs go out; pull fuse 49, the other side, both bulbs go out.
Remove main lighting relay – all 4 bulbs go out.
No pun, any bright ideas of where to go next.
Thanks,
Duncan
