Peak voltage measurement

NOTE:
When checking the condition of the igni-
tion system it is vital to know the peak
voltage.
Cranking speed is dependant on many
factors (e.g., fouled or weak spark plugs, a
weak battery). If one of these is defected,
the peak voltage will be lower than speci-
fication.
If the peak voltage measurement is not
within specification the engine will not
operate properly.
A low peak voltage will also cause compo-
nents to prematurely wear.

Peak voltage adaptor

NOTE:
Throughout this chapter the peak voltage
adaptor's part number has been omitted.
Refer to the following part number.
The peak voltage adaptor should be used
with the digital tester.
Peak voltage adaptor:
YU-39991/90890-03169
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 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.
