What to do if my Kohler Inverter battery is weak or dead?
If your Kohler Inverter battery is weak or dead, recharge or replace the battery. Refer to the spec sheet for the recommended battery CCA rating.
What to do if Kohler Inverter oil level is low?
If the oil level is low, restore it to the correct level. Also, inspect the generator set for any oil leaks.
How to reset controller after overcrank fault on Kohler Inverter?
If there is an overcrank shutdown, 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.
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.
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.
What causes my Kohler Marine Equipment to stop suddenly?
If your Kohler Marine Equipment stops suddenly, check the controller’s LED display for a fault shutdown code. Correct the fault and then move the generator set master switch to OFF/RESET to reset the controller. Also, replace the backfire flame element if clogged. Replace the controller fuse (F2), the auxiliary winding fuse (F1) (and if it blows again, test generator components), and the relay interface board (RIB) fuse (F2) if they are blown. If the engine is overloaded, reduce the electrical load.
Why does my Kohler 7.3ECD-Low CO Marine Equipment lack power?
If your Kohler Marine Equipment lacks power, first reduce the load to address potential overloading. Check the controller settings for unit configuration (UC) and engine type (EC) to ensure the engine is running at the rated RPM. If the issue persists and there is engine power loss, refer to the Engine Service Manual for troubleshooting and repair instructions.
How to troubleshoot a Kohler 7.3ECD-Low CO Marine Equipment that operates erratically?
If your Kohler Marine Equipment operates erratically, start by cleaning or replacing the backfire flame arrestor if it's clogged. Replace and regap the spark plugs. Test or replace components of the ignition system. If the problem continues, clean the cylinder head to remove any carbon buildup in the engine.
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.
