I have a 1960 R.E. 350cc Clipper which I am restoring. The bike was converted to 12V (Green & black alternator wires joined) with the 'mechanical rectifier'. The Alternator needed to be replaced so I ordered one from Royal Enfield. in India, (living in Aus. it is far more economical than having one shipped from the UK.)
I have replaced the mechcanical rectifier/diode with an electronic Regulator/ rectifier and re wired the bikes electrical system. The 6Volt, made in india, Alternator fits well however the three wires from the alternator are of different colours - White, Green & Purple, the old Lucas
Alternator wires were White, Green and Black. Does anyone know which two of the three wires of the Indian made alternator need to be joined to make it into a 12V?
Failing this, is it possible to check the AC voltage from the alternator cable (bike ticking over) after joining various combinations of the three wires and looking for the highest output?
Any assistance would be appreciated
Thank you - Clipper
