Why does my Kohler 6EKOD emit black or gray smoke?
If your Kohler Marine Equipment generator emits black or gray smoke, check the oil level. Also check compression, as the issue might be worn piston rings or valves.
What to do if Kohler Inverter experiences a fault shutdown?
If your Kohler Inverter experiences a fault shutdown, reset the controller.
How to troubleshoot erratic operation of my Kohler 6EKOD?
If your Kohler Marine Equipment operates erratically, adjust the governor stability. Clean the cylinder head to address potential carbon buildup in the engine. Check cylinder pressures with a leakdown test and inspect the valves and valve seats to ensure the engine valves are seating correctly.
What to do if my Kohler Marine Equipment overheats?
If your Kohler Marine Equipment overheats, inspect the cooling system for air intake obstructions. Also, check the engine coolant system for blockages and clean as necessary to ensure adequate cooling.
How to fix a Kohler 6EKOD generator that starts hard?
If your Kohler Marine Equipment generator starts hard, check the battery voltage, power supply, and operation to address potential low battery voltage. Inspect the compression to identify worn piston rings or valves. Also, verify that battery voltage is present at each glow plug (control wire to ground) while cranking. To check glow plug condition, remove each glow plug and measure the resistance from the control wire connection point to the tip of the glow plug; a resistance of approximately 1 ohm indicates a good glow plug.
Why does my Kohler 6EKOD Marine Equipment generator lacks power?
If your Kohler Marine Equipment generator lacks power, inspect air intakes and the exhaust for obstructions to ensure adequate cooling. Check the controller configuration setting and adjust the governor speed to ensure the engine is running at its rated RPM. Test and readjust the governor if there is a malfunction or misadjustment.
What to do if my Kohler 6EKOD starts but shuts down?
If your Kohler Marine Equipment generator starts but shuts down, check the controller’s display for a fault shutdown code. Correct the fault and then reset the controller.
Why my Kohler Marine Equipment cranks but does not start?
If your Kohler Marine Equipment generator cranks but does not start, begin by checking the fuel supply and fuel filters for any blockages. Inspect for loose or open connections at the fuel pump or fuel solenoid, and check the controller/engine wiring continuity. Ensure that the controller configuration settings are correct. Also, check for a locked rotor, which may be indicated by an overcrank fault shutdown.
What to do if my Kohler Marine Equipment generator set does not crank?
If your Kohler Marine Equipment generator set does not crank, there are several potential causes. It could be due to a weak or dead battery, in which case you should recharge or replace the battery. Check for reversed or poor battery connections. Inspect for loose connections or open circuits in the engine/controller connections, and verify the wire harness continuity. Replace the F2 fuse if it's blown; if it blows again, inspect the circuit and components, controller wiring, starter solenoid, and wiring for open grounds, loose connections, or pushed-out pins. Check the crank relay for 12VDC on lead 71N. Clean and retighten any poor ground connections. Inspect the starter and controller connections and operation, ensuring power to the controller.
What to do if Kohler Inverter shows low oil pressure shutdown?
If your Kohler Inverter experiences a low oil pressure shutdown, replace the low oil pressure switch. Also, check the engine for any potential damage.
