Generator light won't go out on my 500!

In the garage deciding what to do first!
As title..........
The bike has a new battery fitted, static voltage is 12,68v.
With the engine started the voltage drops to between 12.35 - 12.45 volts
Revving the bike up to 3K doesn't change the voltage readings - and the light still doesn't go out.

I'm not sure where to start to look for a solution to the problem.........

Well, when you rev it you should get more than 12.45 volts, more like 13 .5 to 14.
That and the fact the light stays on...
Fit a replacement to be sure, not sure how to test one.
 
Had that on a new monty in 82
You should see about 15 volts or higher based on revs
Looks like you need a new regulator

Might want to check the ac voltage going into the regulator
If I remember it was between 15-30 vac  (that was riding)
