Starter Motor Does Not Turn
SAFETY WARNING: Disconnect yellow (starter motor) cable from starter solenoid
test Point 1 BEFORE making tests 1 thru 7 to prevent unexpected engine cranking.
TEST 1 Use an ohmmeter (R x 1 scale) and connect meter leads between negative
(–) battery post and common powerhead ground.
No Continuity Indicated
There is an open circuit in the black negative (–) battery cable
between the negative (–) battery post and the powerhead.
a. Check cable for loose or corroded connections.
b. Check cable for open circuit.
Continuity Indicated
Proceed to TEST 2.
12 Volt Reading*
Check black ground wire for poor
connection or open circuit. reconnect
ground wire to starter solenoid;
proceed to TEST 7.
No voltage reading;
proceed to TEST 3.
TEST 2
a. Disconnect black ground wire from Test Point 2.
b. Connect voltmeter between common engine
ground and Test Point 2.
c. Turn ignition key to “Start” position.
TEST 4
a. Connect voltmeter between common
engine ground and Test Point 4.
b. Turn ignition key to “Start” position.
TEST 5
Connect voltmeter between common
engine ground and Test Point 5.
*Battery Voltage TEST POINTS
Refer to preceding page
for Test Point location.
TEST 3

12 Volt Reading*
Defective ignition switch.
TEST 6
Connect voltmeter between common
engine ground and Test Point 6.
No voltage reading;
check red wire
between battery (+)
positive and Test
Point 6.
12 Volt Reading*
Check fuse (if equipped) in red
wire between test points 5 and
6. Check for open red wire
between Test Points 5 and 6.
TEST 7
a. Connect voltmeter between common
engine ground and Test Point 1.
b. Turn ignition key to “Start” position.
No voltage reading;
defective starter
solenoid.
12 Volt Reading*
Should hear solenoid click;
proceed to TEST 8.
TEST 8
a. Reconnect yellow (starter motor)
cable to starter solenoid Test Point 1.
b. Connect voltmeter between common
engine ground and Test Point 7.
c. Turn ignition key to “Start” position.
No voltage reading;
check yellow cable
for poor connection
or open circuit.
12 Volt Reading*
If starter motor does not turn,
check that starter motor is
grounded to powerhead. If
starter motor is grounded to
powerhead, check starter.
