TROUBLESHOOTING
to RUN?
2. If yes, the problem is probably in the engine harness, engine components or ignition switch.
Disconnect the fuel valve. If the fuse does not blow, the problem is probably in the fuel valve.
3. If, from point 1 above, the fuse does not blow, reattach the hour meter connectors. If the fuse
blows, the hour meter is probably faulty.
4. If the hour meter is OK, reconnect the brake switch and pull the brake on. If the fuse holds,
reconnect the seat switch and turn the ignition to RUN.
5. If the fuse holds, remove and then replace the relays one at time and try again. A blown fuse here
indicates that the relay is faulty.
6. If it has been established that the problem is in one of the safety interlock circuits, that the battery
is delivering 12 volts and that the main fuse is OK, but that the engine will not turn over, the brake
relay can be easily tested as set out below.
Engage the brake, disconnect the brake relay and attempt to start the engine. If the engine now
turns over and the main fuse holds, the brake relay is probably faulty.
• Symptom: Clicking under the console; the engine runs poorly and surges.
Suggested procedure:
1. Disconnect the hour meter. If the symptoms disappear, replace the hour meter.
IMPORTANT INFORMATION
Disconnecting the brake relay bypasses that part of the interlock system which
prevents the mower moving with the brake on.
