PROCEDURE

IMPORTANT: Before proceeding with this test, verify that the engine has normal oil pressure, is not overheated, and the alternator drive belt is in place and properly ten- sioned.

Open all of the doors on the SAE-400 machine.

WARNING: Secure the doors in the open position using the door restraint system. If the machine does not have a door restraint system, remove the doors or securely restrain them to prevent them from falling closed.

1.Disconnect the lead from the engine coolant tem- perature gage or switch.

Code 10856, temp gage, Lead wire #221 Codes 11199 & 11408, temp switch, lead #44

2.Disconnect the lead from the engine oil pressure switch.

Code 10856, lead #223

CAUTION: The following procedure will temporarily disable the engine protection system. Be absolutely certain that engine temperature and oil pressure are within the normal range. If the engine is permitted to run while overheated or with low oil pressure, severe engine damage will likely result, and the engine warranty will not cover the damage. Be absolutely certain that all wires are connected when the test is com- pleted.

3.Disconnect the flash/sense lead from the engine alternator.
