ELECTRICAL ANALYSIS
Measuring step:
Remove the electrical box and disas-
sembly it.
Refer to "ENGINE UNIT" in chapter 5.
Attach the tachometer to the high ten-
sion lead of the cylinder #1, (no need
during cranking measurement).
Set the peak voltage adaptor to the
tester.
NOTE:
The peak voltage adaptor plugs a have
polarity. Connect the red plug of the
peak voltage adaptor to the volt test plug
of the tester.
Set the digital tester dial at the DCV
position.
Connect the peak voltage adaptor
leads b to the correct terminals c or
test harness 1 to be measured.
NOTE:
The peak voltage adaptor leads have
no polarity. Therefore, the measure-
ment will be the same if the leads are
interchanged.
Wire colors for connection purposes
will be indicated.
Connect the water vehicles to a fully
charged battery. (In cranking measure-
ment.)
Start or crank the engine and read the
indication.
CAUTION:
When the peak voltage is measured dur-
ing engine operation, measure it with
cooling water passing through the
engine cooling water passage.
