332-Series: Power Units
(Please see the "help files" for installation instructions.)

If the stator on the bike has 3 wires and you are unsure whether it is single phase or 3 phase, please quote the stamped in Lucas number found on the laminations of virtually all stators.

ALL 2 wire stators are single phase, but 3 wire stators could be single phase or 3 phase. Any stators with more than 3 wires are for the ET (AC ignition) systems and should be replaced by a later stator in order to upgrade, and the ignition modified. Please note, 3 phase stators only came as standard equipment on negative ground equipped Triumph twins from 1979 onwards, but some older bikes have been upgraded with three phase stators for higher output, at lower RPM.

If in doubt, call BCS to discuss.
