What to do if the customer connection fuse (F3) is blown in Kohler Inverter?
If the customer connection fuse (F3) is blown in your Kohler Inverter, replace the blown fuse. If the fuse blows again, check what is connected to the generator set.
What to do if the controller fuse (F2) is blown in Kohler Inverter?
If the controller fuse (F2) is blown in your Kohler Inverter, replace the blown fuse. If the fuse blows again, troubleshoot the controller.
What to do if there is a controller fault in Kohler Inverter?
If the controller of your Kohler Inverter has a fault, troubleshoot the controller.
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 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.
