Lighting coil
Lighting coil output peak voltage
1. Disconnect the lighting coil connectors.
2. Measure the lighting coil output peak
voltage.
3. Measure the lighting coil resistance if
below specification.
TIP:
To crank the engine, connect the engine
shut-off cord to the engine shut-off switch,
and then push the engine start switch and
engine stop switch simultaneously.
Lighting coil resistance
1. Measure the lighting coil resistance.
2. Replace the lighting coil if out of specifi-
cation.
Rectifier regulator
Rectifier regulator output peak voltage
1. Disconnect the rectifier regulator connec-
tors.
2. Measure the rectifier regulator output
peak voltage.
3. Measure the rectifier regulator resistance
if below specification.
