IMPORTANT:
Engine must be in NEUTRAL
throughout test procedure and battery must be
fully charged.
STEP 1
Connect the voltmeter between cable at starter
terminal and ground. Press start button. Check
voltage to cable at starter terminal.
• If voltmeter shows 12 V, test starter.
• If voltmeter shows 0 V, go to STEP 2.
STEP 2
Connect the voltmeter between solenoid connec-
tion A and ground. Check voltage at solenoid con-
nection A.
• If the voltmeter shows 12 V, go to STEP 3.
• If the voltmeter shows 0 V, test the battery and
cables.
STEP 3
Connect the voltmeter between solenoid connec-
tion B and ground. Press the start button. Check
voltage at solenoid connection B.
• If the voltmeter shows 12 V, go to STEP 4.
• If the voltmeter shows 0 V, test start button and
wiring.

STEP 4
Disconnect the yellow/red lead from neutral start
switch. Connect voltmeter between yellow/red
lead and ground. Press start button. Check volt-
age at yellow/red lead.
• If voltmeter shows 12 V, go to STEP 5.
• If voltmeter shows 0 V, replace solenoid or yel-
low/red lead.
STEPS
Connect the yellow/red lead back to the neutral
start switch. Connect voltmeter between solenoid
connection C and ground. Press start button.
Check voltage at solenoid connection C.
• If the voltmeter shows 0 V, replace solenoid.
• If voltmeter shows 12 V, replace starter cable.
