NOTE:
Stop switches include the ignition switch and the engine cut-out switch.
It is important to take note that voltage measurements must be taken while starting the vehicle using the
manual starter.
Voltages obtained upon starting are proportional to the force applied onto the manual starter. A low voltage
is therefore normal under a low cranking force.
Perform testing in the prescribed order and replace any parts not performing according to specifications.
It is important to resume all test when replacing a component.
It not specified, the probe connecting sequence is not important.
INSPECTION OF AC CIRCUIT
ISOLATION
All Electric Start Models
If AC circuit is not isolated from frame, headlamp
beam will weaken.
INSPECTION
Disconnect regulator/rectifier.
On models with hydraulic brake, pull off the rubber
boot from brake light microswitch assembly.
Connect one digital ohmmeter probe (needle ohm-
meter will not offer enough precision) to frame and
other probe to one of 2 YELLOW magneto wires.
Measured resistance must be infinite. If such is
not the case, it means there is a connection be-
tween AC circuit and DC circuit.
Disconnect one accessory at the time to identify
the faulty circuit.
INSPECTION OF HEATING
ELEMENTS
All Skandic Models
All measurements must be performed at 21°C
(70°F).
Throttle Lever Heating Element
Current Measurement
Handlebar Grip Heating Element
Resistance Measurement
➀
When measuring resistance at terminals the ac-
tual value will be half the measurement in table.
The reason for that is the elements are connect-
ed in parallel. Therefore the total resistance is
half the resistance of one element.
