Why is my Kohler Marine Equipment making noisy operation?
If your Kohler Marine Equipment is operating noisily, check the exhaust system for leaks and replace components as necessary. Retighten screws and replace rivets on any loose or vibrating sheet metal or housing. If there's excessive engine/generator vibration, inspect the rotor, crankshaft, and bearings, which may require disassembly of the engine or alternator.
What to do if F7 fuse is blown on Kohler Inverter?
If the starter motor and crank solenoid fuse (F7) is blown, replace it. If it blows again, troubleshoot the controller.
What causes no output voltage in my Kohler Marine Equipment?
If your Kohler Marine Equipment has no output voltage, check if the AC output circuit breaker is open. Verify AC voltage on the generator side of the circuit breaker. If voltage is present, the issue may be a tripped breaker due to a problem in the load circuits. Perform a separate excitation procedure to determine if the problem lies within the alternator or the control system. Check the continuity of wiring, terminals, or pins in the buildup circuit or SCR module circuit. Inspect the brushes and replace them if they are worn.
What to do if F3 fuse is blown on Kohler Inverter?
If the customer connection fuse (F3) is blown, replace it. If it blows again, troubleshoot the controller.
What to do if F4 fuse is blown on Kohler Inverter?
If the coil/injector fuse (F4) is blown, replace it. If it blows again, troubleshoot the controller.
How to replace exhaust temperature switch on Kohler Inverter?
If the high exhaust temperature switch is inoperative, replace the switch.
How to fix a Kohler 7.3ECD-Low CO Marine Equipment that starts hard?
If your Kohler Marine Equipment starts hard, begin by checking the battery voltage. If the voltage is low, it may be the cause. Also, inspect the backfire flame arrestor and clean or replace it if clogged. Examine the spark plugs; replace or regap them as needed. Check the spark plug wires and connections, replacing the wires if necessary. If these steps don't resolve the issue, check the compression to identify worn piston rings or valves. Finally, check the F5 fuse and ECM ground connection pin 14.
Why does my Kohler 7.3ECD-Low CO Marine Equipment start but then shut down?
If your Kohler Marine Equipment starts but then shuts down, check the controller’s LED display for a fault shutdown code. After identifying the fault, correct it and then move the generator set master switch to OFF/RESET to reset the controller.
What to do if my Kohler 7.3ECD-Low CO Marine Equipment cranks but does not start?
If your Kohler Marine Equipment cranks but doesn't start, start by checking the fuel supply. Then, inspect the spark plugs, wires, and connections, replacing or cleaning and regapping the spark plugs as necessary. Look for loose or open connections at the fuel solenoid and engine control module. Ensure the backfire flame arrestor isn't clogged by cleaning or replacing it. Verify correct controller configuration parameters, specifically the unit configuration (UC) and engine configuration (EC). Test or replace ignition system components if needed. Also, check and replace F2, F4, and F5 fuses if they are blown. For F4, check GNDs on coil. For F5, check ECM ground connection pin 14.
How to reset controller after overcrank fault on Kohler Inverter?
If there is an overcrank shutdown, reset the controller.
