Faulty regulator?

<< < (3/3)

Bryanj:
You need to find where the excess volt drop is.
Start at battery +ve and check at connections all way through

Johnny4428:
Yes will do Bryan. I will keep you posted, Thanks.

If it is getting warm at the ignition switch could it be bad connection onto switch (or faulty switch). Difference in voltage between black and white on regulator sounds like dirty points in regulator. Possibly. Didn't know they made a G3 in '61. I had one a while ago or was it an AJS.

Johnny4428:
Thanks Cliff, yes a bit of checking to do tomorrow. Yes I have a post “jampot” model which was originally an MOD bike used by the aux fire team at an aerodrome in Scotland. When I restored it I painted it black.

Johnny4428:
Sorry don’t know why that one was upside down.
