Troubleshooting
6Symptoms & remedies
| Symptom | Remedy |
|---|---|
| Fault lamp lights and engine stops cranking after approximately 75 seconds. | See engine service manual for troubleshooting fuel system, ignition system, etc. After correcting problem, reset the engine monitor by holding run-stop-remote switch in stop position, and depressing reset switch.
