4.Insulate and/or position these leads so they cannot touch chassis ground, any other electrical conduc- tor, or be damaged by any moving parts.

5.Start the engine and allow it to run.

6.If the engine still shuts down, thoroughly check the three wires that had been disconnected in steps 1 through 3. Be particularly aware of damaged insu- lation, or anything that may cause one of these conductors to come in contact with chassis ground.

7.If no problems are discovered with the wiring or insulation, the Idler/Engine shutdown PC board is faulty and should be replaced.

8.If the engine continues to run with these wires dis- connected, one of the engine protections switches is faulty or the engine alternator is faulty.

9.Shut off the engine and reconnect any one of the three leads that had been disconnected in steps 1 through 3, then start the engine and allow it to run. If the engine shuts down, the component that had just been connected is faulty and should be repaired or replaced.

10.If the engine continues to run after reconnecting one of the wires, repeat step #9, connecting one of the two remaining wires, then repeat step #9 again connecting the last wire. Repair or replace any faulty component.

Be certain to reconnect all lead wires and close the doors when testing and service is complete.
