Test
Disconnect the two starter switch leads.
Connect ohmmeter between switch leads. Acti-
vate switch. Meter must indicate resistance as
fol-
lows:
•
Low resistance reading when switch is pressed.
• High resistance reading when switch is
released.
Replace
the start switch if test results are not cor-
rect.

STEP 1
Connect
voltmeter red lead to battery positive (+)
terminal. Connect voltmeter black lead to battery
negative
(-)
terminal. Check the battery voltage.
• If
the voltmeter shows 12
V,
go to STEP 2.
• If the voltmeter shows 0
V,
test the battery.
STEP 2
Move the voltmeter black lead to the rectifier ter-
minal ground. Check the voltage between battery
positive (+)
terminal and rectifier terminal ground.
• If the voltmeter shows 12
V,
go to STEP 3.
• If the voltmeter shows 0
V,
test the negative
(-)
battery cable.

STEP 3
Move the
voltmeter red lead to the start switch
connection. Check the
voltage between the start
switch connection and rectifier
terminal.
• If
the voltmeter shows 12
V,
go to STEP 4.
• If the voltmeter shows 0
V,
test the positive (+)
battery
cable.
STEP
4
Move the
voltmeter black lead
to
powerhead
ground. Check the
voltage between the start
switch connection and powerhead ground.
• If the voltmeter shows 12
V,
go to STEP 5.
• If the voltmeter shows 0
V,
clean and tighten the
rectifier
terminal screw.
STEPS
Move the voltmeter red lead to the start switch
output
lead. Push the start button.
Check
the volt-
age between the start switch output lead and pow-
erhead ground.
• If the voltmeter shows 12
V,
go to STEP 6.
• If the voltmeter shows 0
V,
check the start
switch, start switch wires and start switch con-
nection.
STEP 6
Remove
voltmeter red and black leads. Connect
the start switch output
lead to the starter terminal.
Push the start button. Check for correct operation
of the starter.
• If the starter runs, check the condition of the
pinion.
• If the starter does not run, service the starter.
