Cranking Voltage - Battery Load Test
This test checks the battery to see if it is
delivering enough voltage to the starter motor
under cranking conditions.
5. Connect BLACK test lead to negative (-)
terminal of battery.
6. Turn multimeter rotary switch to 20V
DC range.
7. Crank engine for 15 seconds continu-
ously while observing display.
8. Test Results.

Disconnect the primary of the ignition coil
or the distributor pick-up coil or the cam/
crank sensor to disable the ignition sys-
tem. Refer to vehicle service manual for
disabling procedure.
2. Insert BLACK test lead into COM test
lead jack.
3. Insert RED test lead into
test
lead jack.
4. Connect RED test lead to positive (+)
terminal of battery.
Voltage Temperature
9.6V or greater 70 °F and Above
9.5V 60 °F
9.4V 50 °F
9.3V 40 °F
9.1V 30 °F
8.9V 20 °F
8.7V 10 °F
8.5V 0 °F
If voltage on display corresponds to above
voltage vs. temperature chart, then cranking
system is normal.
If voltage on display does not correspond to
chart, then it is possible that the battery,
battery cables, starting system cables, starter
solenoid, or starter motor are defective.
