1 General information
All models have a 12-volt electrical system
charged by a three-phase alternator with a
separate regulator/rectifier.
The regulator maintains the charging system
output within the specified range to prevent
overcharging, and the rectifier converts the AC
(alternating current) output of the alternator to
DC (direct current) to power the lights and
other components and to charge the battery.
The alternator rotor is mounted on the right-
hand end of the crankshaft.
2.5 A multimeter is capable of reading
ohms, amps and volts
All models are fitted with an electric starter
motor. The starting system includes the
motor, the battery, the relay and the various
wires and switches.
Note: Keep in mind that electrical parts, once
purchased, cannot be returned. To avoid
unnecessary expense, make very sure the
faulty component has been positively
identified before buying a replacement part.

Tracing faults
1 A typical electrical circuit consists of an
electrical component, the switches, relays, etc
related to that component and the wiring and
connectors that hook the component to both
the battery and the frame. To aid in locating a
problem in any electrical circuit, refer to the
2.6a A test light.

Wiring Diagrams at the end of this Chapter.
2 Before tackling any troublesome electrical
circuit, first study the wiring diagram
thoroughly to get a complete picture of what
makes up that individual circuit. Trouble
spots, for instance, can often be narrowed
down by noting if other components related to
that circuit are operating properly or not. If
several components or circuits fail at one
time, chances are the fault lies in the fuse or
earth connection.
3 Electrical problems often stem from simple
causes,
such
as
loose or
corroded
connections or a blown fuse. Prior to any
electrical fault finding, always visually check
the condition of the fuse, wires and
connections
in
the
problem
circuit.
Intermittent failures can be especially
frustrating, since you can't always duplicate
the failure when it's convenient to test. In such
situations, a good practice is to clean all
connections in the affected circuit, whether or
not they appear to be good. All of the
connections and wires should also be wiggled
to check for looseness which can cause
intermittent failure.
4 If testing instruments are going to be
utilised, use the wiring diagram to plan where
you will make the necessary connections in
order to accurately pinpoint the trouble spot.
Using test equipment
5 The basic tools needed for electrical fault
finding include a battery and bulb test circuit,
a continuity tester, a test light, and a jumper
wire. A multimeter capable of reading volts,
ohms and amps is also very useful as an
alternative to the above, and is necessary for
performing more extensive tests and checks
(see illustration).
6 Voltage checks should be performed if a
circuit is not functioning properly. Connect
one lead of a test light or voltmeter to either
the negative battery terminal or a known good
earth (see illustrations). Connect the other
lead to a connector in the circuit being tested,
preferably nearest to the battery or fuse. If the
