ELECTRICAL ANALYSIS
When measuring the peak voltage, con-
nect the peak voltage adaptor to the digi-
tal tester and switch the selector to the
DC voltage mode.
NOTE:
Make sure that the adaptor leads are
properly installed in the digital circuit
tester.
Make sure that the positive pin (the "+"
mark facing up as shown) on the adaptor
is installed into the positive terminal of
the tester.
The test harness is needed for the follow-
ing tests.

Checking steps:
Disconnect the coupler connections.
Connect the test harness between the
couplers.
Connect the tester terminals to the ter-
minals which are being checked.
Run the engine and observe the mea-
surement.
NOTE:
Make sure the output lead (red lead) of the
rectifier/regulator is disconnected when
measuring the peak voltage of the lighting
coil and rectifier/regulator.
If the lighting coil and pickup coil(s) are
measured unloaded, disconnect the test
harness on the output side coupler.
