ELECTRICAL ANALYSIS
Set the digital tester dial at the DCV posi-
tion.
Connect the peak voltage adaptor leads
b to the correct terminals to be mea-
sured.
NOTE:
The peak voltage leads have no polarity
connection of either lead to either termi-
nal c for measurement will result in the
same measurement.
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 in-
dication.
CAUTION:
When the peak voltage is measured dur-
ing engine operation, measure it with
cooling water passing through the en-
gine cooling water passage.
NOTE:
Before measuring cranking, remove the
spark plug caps from the spark plug.
Cranking speed changes the output
measurement.
The specified values shown in the
manuals will be indicated as the lower
limit of the specification. If the meter's
reading is higher, then there is no prob-
lem with the tested component.
If the output reading is lower, then the
component is probably faulty, as long as
the component's input voltages are cor-
rect at the time when testing.
