ELECTRICAL ANALYSIS
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 man-
uals will be indicated as the lower limit
of the specification. If the meter's read-
ing is higher, then there is no problem
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
correct at the time when testing.
LOW RESISTANCE MEASUREMENT
NOTE:
When measuring a resistance of 10 Ω or
less with the digital tester, the correct
measurement
because of the tester's internal resistance.
To obtain the correct value, subtract the
internal resistance from the displayed
measurement.
The internal resistance of the tester can be
obtained by connecting both of its termi-
nals.
