2. Measure:
●
Pickup coil output peak voltage
Below specification
→
Replace the
pickup coil.
NOTE:
The starter motor will not operate when the
test harness on the output side coupler is
disconnected to measure the unloaded
peak voltage for the pickup coil(s). There-
fore, connect the black lead of the test har-
ness to the ground with a lead.
3. Measure:
●
Lighting coil output peak voltage
Below specification
→
Replace the
lighting coil.
NOTE:
●
Make sure the output lead (red lead) of the
rectifier/regulator is disconnected when
measuring the output peak voltage.
●
The starter motor will not operate when
the test harness on the output side cou-
pler is disconnected to measure the
unloaded peak voltage for the lighting
coil. Therefore, connect the black lead of
the test harness to the ground with a lead.
