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.
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.
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 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 does my Kohler 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.
How to fix a Kohler 7-9EFKOZD Marine Equipment 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.
What to do if my Kohler 7-9EFKOZD 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.
What to do if Kohler Inverter experiences a fault shutdown?
If your Kohler Inverter experiences a fault shutdown, reset the controller.
What causes low output voltage on my Kohler 7-9EFKOZD Marine Equipment?
If your Kohler Marine Equipment generator has low output or excessive voltage drop, reduce the load if the generator is overloaded. Check and adjust the controller configuration settings and voltage settings. Inspect the harness connections, P2 plug, and F1 fuse connections for intermittent wiring connections or lack of compression. Also, check the controller settings, fuse, wiring, and connections.
Why does my Kohler 7-9EFKOZD 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.
