Alternator

Copied from my other post, what I want to do is buy a new alternator and I was wondering which one to fit. The 74mm diameter rotors and matching stator seem to be easy to get hold of, but I don't know which part to get. My current alt is a 70mm diameter rotor and the diameter of the stator is 127mm. Is it Rm20 and RM21 I need?

Hello Neil,
70 mm rotors/stators are now unavailable, except in autojumbles.
I can recommend Paul Goff who can supply brand new 74 mm rotor/stator, 6 or 12 volts, 2 wires, 3wires, triphase, and suitable regs.
Kind regards. J.N.
