Starter Motor Turns For Starting But Will Not Turn For Reverse Running - Honda GL1800 Service Manual

Starter motor turns for starting but will not turn for reverse running

1. Side Stand Switch Signal Line Continuity Inspection
• Make sure the following conditions are satisfied for reverse running:
– engine is running
– transmission is in neutral
– side stand is retracted
– reverse shift switch is pushed to "ON" and the reverse indicator illuminates.
• When the speed limiter is activated during reverse running, followed by the electrical motor brake
or when the motor is overloaded more than 3 seconds, the reverse system is turned off and the
reverse indicator goes out. To use reverse again, it is necessary to push the reverse shift switch to
"OFF," then push it to "ON."
Check the side stand switch (No. 11) circuit at the cruise/reverse control module (page 19-39).
Is continuity correct?
NO – Open circuit in the Green/white wire between the cruise/reverse control module and side
stand switch.
YES – GO TO STEP 2.
2. Oil Pressure Switch Signal Line Continuity Inspection
Check the oil pressure switch (No. 48) circuit at the cruise/reverse control module (page 19-39).
Is continuity correct?
NO – • Short circuit in the Blue or Blue/red wire between the control module and oil pressure
switch.
• Faulty oil pressure switch diode (D18) (page 20-13).
YES – GO TO STEP 3.
3. Starter Relay Switch B Cable Continuity Inspection
Remove the left saddlebag (page 2-15).
Check for continuity between the cable terminals at starter relay switch B.
There should be continuity.
Is there continuity?
NO – • Open circuit in the Red wire between starter relay switch B and reverse resistor
assembly.
• Open circuit in the Black wire between starter relay switch B and reverse resistor
assembly.
• Loose or poor contact of the related connectors and terminal.
• Faulty reverse resistor assembly (page 19-30).
YES – GO TO STEP 4.
4. Starter Relay Switch A Relay Coil Voltage Line Inspection
Measure the regulated voltage of the reverse regulator assembly at the starter relay switch A 2P con-
nector (page 19-28).
Is battery voltage present?
NO – GO TO STEP 5.
YES – Temporary failure; the system is normal.
5. Starter Reverse Switch Signal Line and Reverse Relay Coil Control Line Voltage Inspection
Check the starter/reverse switch (No. 18) circuit and reverse relay (No. 43) circuit at the cruise/
reverse control module (page 19-39).
Is battery voltage present?
NO – • Open circuit in the Yellow/red wire between the cruise/reverse control module and
starter/reverse switch.
• Open circuit in the Yellow/red wire between the cruise/reverse control module and
reverse relay.
• Loose or poor contact of the related connectors.
YES – GO TO STEP 6.
