What to do if Kohler Inverter has high temperature shutdown?
If there is a high temperature shutdown, allow the engine to cool down, and then troubleshoot the cooling system, adding coolant if necessary.
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 4EFCD-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 4EFCD-Low CO 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.
Why is my Kohler Inverter vibrating excessively?
If there is excessive vibration, tighten all loose hardware.
How to reset the circuit breaker on a Kohler Inverter?
If the controller circuit breaker tripped, reset it.
How to restore coolant level in Kohler Inverter?
Restore the coolant to the normal operating level if it is low.
Why is my Kohler 4EFCD-Low CO 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 causes no output voltage in my Kohler 4EFCD-Low CO?
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.
