Checking the lighting coil
1. Remove the Rectifier Regulator cover, and
connect the digital circuit tester lead to the
lighting coil.
2. Measure the lighting coil output peak volt-
age. If the measurement is below specifi-
cation, check the lead and measure the
lighting coil resistance. Replace if neces-
sary.

Checking the Rectifier Regulator
1. Remove the Rectifier Regulator cover, and
connect the digital circuit tester lead to the
Rectifier Regulator.
2. Measure the Rectifier Regulator output
peak voltage. Replace the Rectifier Regu-
lator, if the lighting coil output peak voltage
is on or above specification and the Recti-
fier Regulator output peak voltage is be-
low specification.

NOTE:
Disconnect the output lead (Red(R)- Black(B))
of the Rectifier Regulator when measuring the
output peak voltage.
