Kohler 35EFKOZD Generator Set

1. If desired, the digital display can be gimbal mounted.
2. Source gimbals from RAM Mounting Systems, Inc. at www.ram-mount.com.
3. Use the RAM Diamond base with 9/16 in. ball, part number RAM-A-238, matching the display bolt pattern.

1. Select a dry location in the wheelhouse or bridge.
2. Confirm wiring harness length and mounting depth and overall size.
3. Use Figure 5 and Figure 6 for display mounting dimensions.
4. For single display, connect the 6-pin plug end of the harness to connector B on the display.
5. For multiple displays, connect the 6-pin plug end of the harness to an extension harness or Y-harness as needed.
6. Connect the terminal ends of the harness to terminal strip TB12 inside the junction box.
7. Do not exceed 91.4 m (300 ft.) CAN network length.

1. Check CAN+ and CAN- at the terminal strip in the junction box for 120 ohms on the controller with controller powered down.
2. If measuring 120 ohms, a terminating resistor already exists in the controller and no second resistor is needed at the controller.
3. Place one 120 ohm terminating resistor at the furthest end from the controller.
4. If using multiple extension harnesses, remove all other terminating resistors from the extension harnesses by disconnecting the cap.
5. Place one 120 ohm terminating resistor at the controller end of the harness unless the controller has a built-in resistor.
6. After everything is connected, verify 60 ohms on CAN+ and CAN-.

⚠ Accidental starting can cause severe injury or death. Disconnect battery cables before working on generator set; remove negative lead first and reconnect it last.

⚠ Do not cut or splice the harness; do not select a longer harness.

1. Remove generator set from service: press OFF/RESET, disconnect battery charger, disconnect starting batteries negative lead first.
2. Remove junction box cover/panels as needed to access controller wiring.
3. Remove four controller panel screws and mark all disconnected controller leads with tape.
4. Disconnect P1 35-pin, P2 14-pin, P3 8-pin, P4 Ethernet, and any other external controller leads.
5. Remove controller; save mounting hardware and gasket.
6. Place new controller gasket GM88990 and remote circuit board mounting panel GM96382 in controller opening; studs face into junction box.
7. Secure remote circuit board mounting panel using existing hardware removed in step 2.4.
8. Place two spacers X-712-13 on each of the eight studs on back of mounting panel.
9. Place remote interconnect circuit board assembly GM96419 on eight studs and secure with hex nut X-70-12 at each stud.
10. Connect existing engine harness connectors to back of remote interconnect circuit board assembly.
11. Connect remote controller harness GM96428 to front of remote circuit board mounting panel.
12. For 40-200EOZDJ/33-175EFOZDJ sound-shielded units, install sound shield panel GM95799, gasket GM88990, four screws, four washers, and bushing X-634-29; route harness through opening.
13. Connect other end of controller harness to remote Decision-Maker 3500 controller, reusing existing controller gasket.
14. Secure wiring with rubber grommets and cable ties; conform to USCG CFR Title 33 Parts 183.425 through 183.460.
15. Replace removed panels; verify set OFF, reconnect battery negative lead last, reconnect battery charger, start and verify metering, then stop.

⚠ Accidental starting can cause severe injury or death. Disconnect the battery cables before working on the generator set.

1. Press the generator set OFF/RESET button to shut down the generator set.
2. Disconnect power to the battery charger, if equipped.
3. Disconnect the generator set engine starting battery(ies), negative (-) lead first.

1. Check that the generator set is OFF.
2. Reconnect the generator set engine starting battery, negative (-) lead last.
3. Reconnect power to the battery charger, if equipped.
