STARTER SYSTEM TESTING FLOW CHART

Condition: Starter fails to turn motor. NOTE: Make sure engine crankshaft is free to turn
before proceeding with dynamic testing of starter system. A digital multitester must be used
for this test
With the tester on the VDC position, place the
tester's black lead on the battery negative and the
red lead on the battery positive. Reading should
be 12.4 V D. C. or greater.
Yes
Disconnect coil engagement wire from the starter
solenoid. Connect tester black wire to battery
ground. Connect red tester lead to harness wire at
solenoid. Turn on ignition switch and depress the
starter button. Tester should read battery voltage.
Voltage Drop
Testing
Reconnect the solenoid. Connect the tester black
lead to the battery positive and the red lead to the
solenoid end of the battery-to-solenoid wire.
Depress starter button. Reading should be less
than .1 V D.C.
Connect the black tester lead to solenoid end of
battery-to-solenoid cable. Connect red tester lead
to solenoid end of solenoid-to-starter cable.
Depress starter button. Reading should be less than
.1 V D.C.
Yes
Connect the black tester lead to the solenoid end of
the solenoid-to-starter cable. Connect the red
tester lead to the starter end of the same cable.
Depress the starter button. The reading should be
less than .1 V D.C.
If all of these indicate a good condition, yet the starter still fails to
turn, the starter must be removed for static testing and inspection.
10.44
Test starter solenoid coil by connecting an ohmmeter between the solenoid
wire and the solenoid mounting plate. Resistance should be 3.4
Yes
solenoid ground path by measuring resistance between mounting plate and
battery negative terminal (-).
Yes
Yes
Remove battery and properly service. Install
No
fully charged shop battery to continue test.
Check voltage on both sides of circuit
breaker, ignition switch/engine stop switch
and starter button. The voltage on both sides
No
should be the same. NOTE: The ignition
switch and engine stop switch must be on and
the starter button depressed.
