ALTERNATOR MODEL RM15
The alternator consists of a spigot-mounted 6-coil laminated stator bolted to the outer
portion of chaincase with a rotor carried on and driven by an extension of the crankshaft.
The rotor has an hexagonal steel core, each face of which carries a high energy permanent
magnet keyed to a laminated pole tip. The pole tips are riveted circumferentially to
brass side plates, the assembly being cast in aluminium and machined to give a smooth
external finish.
Thus there are no rotating windings, commutator, brush-gear, bearings or oil seals and
consequently the alternator requires no maintenance apart from occasionally checking
the snap connectors in the three output cables are clean and tight, which are located
behind the frame cover which is located by two knurled screws.

If it is necessary, for any purpose, to remove the rotor, there is no necessity to fit keepers
to the rotor poles. When the rotor is removed wipe off any metal swarf which may
have collected on the pole tips. Place the rotor in a clean place.
N O R M A L R U N N I N G
Under normal running conditions (i.e., ignition switch in IGN position) electrical energy
in the form of rectified alternating current passes through the battery from the alter-
nator—the rate of output depends on the position of the lighting switch. When no
lights are in use, the alternator output supplies the ignition coil and trickle-charges the
battery. When the lighting switch is turned, the output is automatically increased to
meet the additional load of the parking lights and again when the main bulb is in use.
EMERGENCY STARTING
An EMERGENCY starting position is provided in the ignition switch for use if the battery
has become discharged. Under these conditions, the alternator is connected direct to
the ignition coil, allowing the engine to be started independently of the battery.
Once the engine is running, turn the ignition switch back to the normal running position.
otherwise misfiring will occur.
