ELECTRICAL ANALYSIS
S Set the digital tester dial at the DCV posi-
tion.
S Connect the peak voltage adaptor leads b
to the correct terminals to be measured.
NOTE:
S The peak voltage leads have no polarity
Connection of either lead to either terminal
c for measurement will result in the same
measurement.
S Wire colors for connection purposes will be
indicated
S Connect the water vehicles to a fully
charged battery. (In cranking measure-
ment)
S Start or crank the engine and read the in-
dication.
CAUTION:
When the peak voltage is measured during
engine operation, measure it with cooling
water passing through the engine cooling
water passage.
NOTE:
S Before measuring cranking, remove the
spark plug caps from the spark plug.
S Cranking speed changes the output mea-
surement.
S The specified values shown in the manuals
will be indicated as the lower limit of the
specification. If the meter's reading is high-
er, then there is no problem with the tested
component.
S If the output reading is lower, then the com-
ponent is probably faulty, as long as the
component's input voltages are correct at
the time when testing.
