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.
4. Connect RED test lead to positive (+)
terminal of battery.
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
continuously while observing display.
8. Test Results.
Compare display reading in Step 7 with
chart below.

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.
