Starter Motor - - Troubleshooting
Condition: Starter fails to turn motor or motor turns slowly.
CAUTION:
Make sure that engine crankshaft is free to turn before proceeding.
With the tester on Vdc, place the tester black lead
on the battery negative (-) terminal and the tester
red lead on the battery positive (+) terminal.
Reading should be 12.4 V or greater.
Is it?
Disconnect the red engagement coil wire from the
starter solenoid. Connect the black tester wire to
an appropriate ground and the red lead to the red
harness wire at the solenoid. Push the start
button. The meter should read battery voltage.
Does it?
Reconnect the solenoid. Connect the tester black
lead to the battery positive terminal and the red
tester lead to the solenoid end of the
battery-to-solenoid cable. Push the start button.
The reading must be less than .1 Vdc. Is it?
Connect the black tester lead to the solenoid end
of the battery-to-solenoid cable and the red tester
lead to the solenoid end of the solenoid-to-starter
cable. Push the start button. The reading must
be less than .1 Vdc. Is it?
Connect the black tester lead to the solenoid end
of the solenoid-to-starter cable and the red tester
lead to the starter end of the same cable. Push
the start button. The reading must be less than
.1 Vdc. Is it?
Connect the black tester lead to the starter frame.
Connect the red tester lead to the battery
negative terminal. Push the start button.
Reading should be less than .1 Vdc. Is it?
If all these tests indicate a good condition, yet the
starter still fails to turn, or turns slowly, the starter
must be removed for static testing and inspection.
