CORRECTIVE ACTION
Turn off the machine. Disconnect the negative on the battery. Check
lead 234, connected to the oil pressure switch, located on the left side
of the engine below the alternator. Check ECU wiring.
Check to see if the load is above the rated output of the machine.
Check the fan belt. Check the fan blade. Check oil level. Inspect inside
machine to see if any debris is preventing proper airflow from being
provided to the engine and radiator. Open the engine service door and
allow the coolant temperature to cool down to ambient. Once the
engine is cooled, check the coolant level. Ensure the coolant level is
always above the fins of the radiator and at the neck. If the cause is
electrical, turn off the machine, disconnect the negative, and check
leads 241 and GND-S, as well as the connector connected to the
coolant sensor located on the left side of the engine, above the
Turn off the machine. Disconnect the negative on the battery. Check
leads 241 and GND-S, as well as the connector connected to the
coolant sensor located on the left side of the engine, above the
Turn off the machine. Disconnect the negative on the battery.
Confirm the battery voltage with a multimeter. If incorrect the ECU
requires a recalibration. If the voltage is correct, turn the machine on
but, do not start the engine. This will allow the battery to discharge.
Turn off the machine. Disconnect the negative on the battery. Check
speed sensor connector, located on the right side of the engine, above
the oil filter, to ensure it is properly connected. Inspect leads
57, 57N, and 57P to ensure they are properly connected to the
connector and have no rips or tears in the leads or sleeving. If the
speed of the engine is exceeding 4100 rpm and the problem is not
electrical, please call your Lincoln service provider.
Turn off the machine. Disconnect the negative on the battery. Ensure
leads 58 and 58N are both connected securely to the actuator
connector, located on the right side of the engine towards the fan.
Inspect both leads for rips and tears in sleeving.
Turn off the machine. Disconnect the negative on the battery. Check
speed sensor connector, located on the right side of the engine, above
the oil filter, to ensure it is properly connected. Moreover, inspect 57,
57N, and 57P to ensure they are properly connected to the leads
connector and have no rips or tears in the leads or sleeving.
Turn off the machine. Disconnect the negative on the battery. Check
the battery voltage. Check leads CAN H and CAN L, located on the left
side of the machine coming out of the ECU harness and the PCB
harness. Inspect the alternator including all leads going into the unit.
Turn off the machine. Disconnect the negative on the battery. Inspect
the L terminal connected to the alternator. Ensure it is connected
correctly. Furthermore, check leads 233A and 100 coming out of the L
connector for rips and tears in the leads.
