3 phase Alternator

He is also in the process of fitting the superb Shindengen SH775 regulator/rectifier – a sensible choice if you are going to fit a lithium-based battery.

In lieu of the twin 6 volt coils, Tim has gone with the dual output single tower coil from Colorado Norton Works (it’s the brilliant Crane Cams unit)
