Neutral light..... This can't be right!

Post by W109driver »



This can't be right.
When I pull the clutch in the neutral light comes on.
Meaning you never know if you actually have neutral until you start letting the clutch out.
Could this be anything to do with my 7v regulator that is faulty?
Thanks

No, the diode between the clutch switch circuit and the neutral light circuit is shorted. Under the left shelter cover, one of the four brown blocks. Look for one with a yellow wire with a red stripe. Made so the starter relay will engage when the clutch is pulled, but will not backfeed the neutral light.

Thanks for that.
Could the 7v regulator, now giving 12.3v have burnt it out?
Expensive part?
Would WingAdmin got one of these?
I'll pm him/them.

7v regulator is a different circuit entirely.

You don't have to use a Honda part to replace this diode. Any garden variety diode rated 1 amp or better will work. Do you have electronics parts suppliers around? A 1N4001 would be fine, you'd just have to adapt the connections. Probably cost less than half a Pound.

Note that current can only flow one direction thru a diode, if you have it connected backward things wont work right, reverse the connections to the diode and check again.

Ok. A friend has a 1 amp diode.
So I'll swap it in, but where am I looking for it in the bike?
Thankyou.
