J1-9 CDL- J1-5 -Battery Expected Result:The resistance is greater than 20000 Ohms.Results:
OK - The resistance is greater than 20000 Ohms. Go to Test Step 4.
NOT OK - The resistance is NOT greater than 20000 Ohms. A short circuit exists.Repair: Repair the harness or replace the harness.STOPTest Step 4. MEASURE THE RESISTANCE THROUGH THE MARINE JUNCTION BOX (OPEN CIRCUIT TEST).
Disconnect the MJB-ECM cable from the MJB.
Disconnect the CDL cable from the marine junction box.
Measure the resistance between the CDL connector and the MJB-ECM cable connector on the marine junction box. Refer to Table 3.

22 CDL+ 6 Expected Result:The resistance is less than 10 Ohms.Results:
YES - The resistance is less than 10 Ohms. Go to Test Step 5.
NO - The resistance is NOT less than 10 Ohms. There is an open circuit in the marine junction box.Repair: Temporarily replace the marine junction box. Recheck to ensure the resistance is less than 10 Ohms.STOPTest Step 5. MEASURE THE RESISTANCE THROUGH THE MARINE JUNCTION BOX (SHORT CIRCUIT TEST).
The MJB-ECM harness remains disconnected.
The CDL cable remains disconnected from the marine junction box.
Measure the resistance between the pins that are listed in Table 4.

YES - The resistance is less than 10 ohms. Go to Test Step 6.
NO - The resistance is greater than 10 ohms. There is an open circuit in the marine junction box.Repair: Temporarily replace the marine junction box. Recheck to ensure the resistance is less than 10 Ohms.STOPTest Step 6. MEASURE THE RESISTANCE THROUGH THE CDL DATA RUN (OPEN CIRCUIT TEST).
Disconnect the CDL cable from the marine junction box.
Disconnect all displays from the CDL and disconnect all service tools from the CDL.
Install a jumper between pin 5 and pin 6 on the CDL connector to the marine junction box.
Measure the resistance between the CDL+ (Pin D) and the CDL- (Pin E) on the CDL connector to the marine junction box. Wiggle the harness during the measurement in order to reveal an intermittent condition. Expected Result:The resistance is less than 20 Ohms.Results:
OK - The resistance is less than 20 Ohms. Go to Test Step 7.
NOT OK - The resistance is greater than 20 Ohms.Repair: Repair the harness or replace the harness.STOPTest Step 7. MEASURE THE RESISTANCE THROUGH THE CDL (SHORT CIRCUIT TEST).
Disconnect the CDL cable from the marine junction box.
Disconnect all displays
