Troubleshooting
Starter Motor Does Not Run
• Battery discharged
• Loose or faulty battery cables or corroded
connections (see Voltage Drop Tests)
• Related wiring loose, disconnected, or corroded
• Poor ground connections at battery cable, starter
motor or starter solenoid (see Voltage Drop Tests)
• Faulty key switch
• Faulty starter solenoid or starter motor
• Engine problem - seized or binding (can engine be
rotated easily)
Starter Motor Turns Over Slowly
• Battery discharged
• Excessive circuit resistance - poor connections
(see Voltage Drop Test)
• Engine problem - seized or binding (can engine be
rotated easily)
• Faulty or worn brushes in starter motor
Starter Motor Turns - Engine Does Not Rotate
• Faulty starter drive
• Faulty starter drive gears or starter motor gear
• Faulty flywheel gear or loose flywheel
Voltage Drop Test
The Voltage Drop Test is used to test for bad connections.
When performing the test, you are testing the amount of
voltage drop through the connection. A poor or corroded
connection will appear as a high voltage reading. Voltage
shown on the meter when testing connections should not
exceed 0.1 VDC per connection or component.
To perform the test, place the meter on DC volts and place
the meter leads across the connection to be tested. Refer
to the voltage drop tests on the starter system in this
chapter.
Starter Motor Removal
1. Disconnect the negative (-) battery cable and remove
the seat base.
2. Remove the positive (+) battery cable from the starter
motor.
3. Remove the nut securing the negative (-) battery
cable from the lower starter mounting bolt.
4. Remove the (2) starter motor mounting bolts. The
routing bracket (A) is mounted to the upper starter
motor bolt.
5. Remove starter from the engine. Use a soft, rubber
hammer to aid in starter removal.
Voltage should not exceed
.1 DC volts per connection
