Interesting... yeah, I can flick the switch to position 1 (driving lights) and its fine, flick to position 2 and nothing, so I can't drive at night If I press and hold the high beam button in (for flashing idiots who cut in front of me ) it works just fine. Bulbs seem fine.

The indicators issue is most likely a separate as they've been getting progressively worse over time and went completely before the lights issue cropped up. Think I need a whole new switch to fix that issue, or could this purely be a relay problem?

I wish I knew how to use a multi-meter correctly to fault find these issues

Likes been said, strip the switch gear right down and clean the brass contacts up. Be very carefull cos theres usually some very small springs and ball bearings in there that love to fly out and disappear!
Cheers

I did that already unfortunately, made no difference :/ Either the relay is knackered or the switch is.

To determine if the turn relay is faulty, disconnect the turn relay and link the black/red wire to the grey wire. When you set the turn switch to left and right, the associsated lamps should illuminate. If they do, then the wiring and lamps are ok and the relay must be faulty. If the lamps do not illuminate then there is a wiring/lamp fault.

Regarding the headlight issue, low beam does not work but high beam and high beam flash do work.

To try another switchgear, you just need to unplug it (on the left side of the front head) -- no need to remove it for that.

Sorry, another stupid question but can someone clarify "left side of the front head"? Do I need to take off the tank because the cable from the switchgear is going under the tank.

The connector should be on the left hand side of the bike near the frame.

If it's running under the tank then someone has routed it incorrectly, best to investigate and do what it takes to remove it.

Thanks for that magg, exactly the kind of info i needed; I'm pretty useless with electrics. I'll give that a go one of the evenings this week to get to the bottom of the issue once and for all.

Shigsy, after rereading my last comment regarding your headlight problem it my not be clear that I am asking a question. I was trying to establish the exact nature of the problem.

Also with your turn indicator problem you should check that the green wire at the turn relay has zero resistance to chassis earth.

Yep, low beam does not work but high beam and high beam flash do. Any ideas?

Is your NC30 a UK model with a low beam relay?
