Peak voltage measurement
NOTE:
9
When checking the condition of the igni-
tion system it is vital to know the peak
voltage.
9
Cranking speed is dependant on many
factors (e.g., fouled or weak spark plugs,
a weak battery, etc.). If one of these is
defected, the peak voltage will be lower
than specification.
9
If the peak voltage measurement is not
within specification the engine will not
operate properly.
9
A low peak voltage will also cause com-
ponents to prematurely wear.
Peak voltage adaptor
NOTE:
9
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 circuit tester.
