Right, I replaced a bulb for my indicators, NSF had blown. Almost imperceptible break so I didn't think there would be much of a problem. Replaced bulbe no problem, and tested and all indicators working fine.

When I tested the hazards on a whim, Only the right side indicators are operating including the dash indicator light?
Now I've studied the circuit diagram and am I right in thinking that the primary place to start would be the hazard warning switch?
I assume that there is a problem with the switch which would require strip down, clean, reassemble and test?

Or am I barking up the wrong tree?

I take it that the RH indicators are now working normally on the indicator switch - just not working on the hazard switch?
That will be a faulty switch, as you say. Not the usual thing that goes wrong with it, but the same cure of strip it down, clean it up, lubricate and reassemble, will cure it just the same.

Yeah, the only issue was with the front bulb gone, all other indicators working fine.
Good, I hoped it was the switch, I think I have a spare switch somewhere but I may as well get this one working again if I can, as I have no idea where I've put the spare.

Thank you for the confirmation Brian.
