DEFLECTOR AS 4838016 - Caterpillar

Expected Result:The resistance is greater than 20000 Ohms.Results:
OK - The resistance is greater than 20000 Ohms. Proceed to Test Step 8.
NOT OK - There is a short circuit in one or more of the wire harnesses. Remove each wire harness. Recheck in order to ensure the resistance is greater than 20000 Ohms.STOPTest Step 8. CHECK FOR SHORT CIRCUITS IN THE MARINE JUNCTION BOX.
Disconnect the MJB-ECM harness.
Disconnect the J1939 data link trunk cable from the marine junction box.
Refer to table 4. Measure the resistance between the pins that are listed.

25 J1939 data - 29 -Battery Expected Result:The resistance is greater than 20000 Ohms. Results:
OK - The resistance is GREATER THAN 20000 Ohms. Go to Test Step 9.
Not OK - The resistance is LESS THAN 20000 Ohms. There is a short circuit in the marine junction box. Repair: Temporarily replace the marine junction box. Recheck in order to ensure the resistance is greater than 20000 Ohms.STOPTest Step 9. CHECK FOR AN OPEN CIRCUIT IN THE DROPS FOR THE MARINE POWER DISPLAY UNITS.
Disconnect the harness between the marine junction box and the ECM.
Disconnect all marine power displays from the data link.
Remove the termination resistor from the last TEE connection for the marine power display.
Measure the resistance between pin 7 and pin 8 on the harness connector for each marine power display. Wiggle the harness during the measurement in order to reveal an intermittent condition. Expected Result:The resistance is greater than 20000 Ohms.Results:
OK - The resistance is greater than 20000 Ohms.Repair: Temporarily replace the marine power display. Recheck in order to ensure the resistance is greater than 20000 Ohms.STOP
NOT OK - The resistance is less than 20000 Ohms.Repair: Repair the harness or replace the harness.STOP
