Reverse Running Speed Too Slow (Below 0.6 Mph (1.0 Km/H) On A Flat Road), Lack Of Uphill Power; Speed Limiter System Will Not Works When The Reverse Running Speed Is Above 1.6 Mph (2.5 Km/H) - Honda GL1800 Service Manual

Reverse running speed too slow (below 0.6 mph (1.0 km/h) on a flat road), lack of uphill power

1. Battery voltage Inspection
Check the battery (page 17-6).
Is battery voltage within the specified value?
NO – • Under charged battery.
• Faulty battery.
YES – GO TO STEP 2.
2. Power Control Relay Inspection
Check the power control relay system (page 19-31).
Does the power control relay system test OK?
NO – • Faulty power control relay circuits.
• Faulty power control relay.
YES – GO TO STEP 3.
3. Reverse Resistor Assembly Inspection
Check the reverse resistor assembly (page 19-30).
Is the resistance correct?
NO – Faulty reverse resistor assembly.
– Faulty cruise/reverse control module.

Speed limiter system will not works when the reverse running speed is above 1.6 mph (2.5 km/h)

1. Speed Limiter Relay System Inspection
Check the speed limiter relay system (page 19-33).
Does the speed limiter relay system test OK?
NO – • Faulty speed limiter relay circuits.
• Faulty speed limiter relay.
YES – GO TO STEP 2.
2. Speed Limiter Line Continuity Inspection
Check the Yellow wire for continuity between the speed limiter relay connector and speed limiter
fuse terminal in the fuse box.
There should be continuity
Is there continuity?
NO – Open circuit in the Yellow wire between the speed limiter relay and fuse box.
YES – GO TO STEP 3.
3. Reverse Resistor Assembly Inspection
Check the reverse resistor assembly (page 19-30).
Is the resistance correct?
NO – Faulty reverse resistor assembly.
YES – Faulty cruise/reverse control module.
