Scooterotica

M8 rung me took scoot for mot failed on a few bits now sorted other than a flickering light standard li runs starts and rides sweet electronic kit fitted can't look till Tom ideas chaps thanx jazzy

Dodgy earth!?

Loose connections at the bulb holder or junction box or bad earths, look for those first.

All connections seem ok could it be a dodgey rectifier ?

As a test take a brown direct to the headlight by removing the red or blue. If it's stable I would be looking at the switch be it the bar one or a key switch. Key ones can be crap bar ones often need the post contacts cleaning. This will also prove the regulator and earths at the headset

Cheers monty

Now sorted faulty regulator
