It consists of a Permanent Magnet Alternator (PMA) and a Regulator.This permanent magnet alternator (PMA) is a 10 pole rotating magnet type generator.It is a simple construction consisting of a stator and rotor. The rotor is made up of tenpermanent magnets, alternator body and magnet retainer mounted on the flywheel.The stator has ten poles with coils and is mounted on the rear plate. The stator goesinside the rotor.Coils are installed with heat insulating washers. The coils are positioned such that thecoil on the side of the engine with cylinders #1 & #3 has it’s output lead pointing downto the distributor. Output lead from coil on cylinder #2 & #4 side of the engine pointsup, then is curled down to the distributor cap – Generally, the output leads followdirection of prop rotation. Coils are set at a gap of between .010” - .012”This document is controlled while it remains on the Jabiru server.
