ELECTRICAL ANALYSIS
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.
●
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.
