Question about Kohler Electrical Supplies

1 Answer

I have a Kohler Confidant 5 LP unit that was running great. Now nothing. It cranks great but will not start. It has spark and the fuel sol. is working, but can not tell if it's getting fuel. Can smell it but can't tell if it's getting into the carb. It does have compression too. Any thoughts would be helpful

Have you checked for a bad head gasket?

Check the intake valve springs or the intake valve shafts to be sure they aren't stuck open. Another cause could be excessive carbon build up on the intake valve causing them to not seal.

If you've gone this far, you could try a compression leak down test. If you still have the push rods out, you can use or get an adapter that will allow you to pressurize the cylinder(s) with air by removing the spark plug. Apply 70-80 psi air directly to the cylinder (the cylinder may go to BDC (bottom dead center) but if you don't have any push rods, the valves can't open.

Listen carefully - if you hear air leaking out of the carb, it's a bad intake valve. If you hear air from the exhaust, it's an exhaust valve. If you hear air from the crankcase breather, it's piston rings.

SOURCE: My Kohler Confidant IV generator starts and runs

Kohler generators feed the generated voltage back into the control circuit board to tell it to keep the fuel pump (electric) runing and the ignition on. IF there is no voltage generated (bad brushes or?) then the symptom you describe will occur. The motor runs fine, but it isn't generating electricity.

First thing is to check oil level as low oil pressure will shut it down.

It is not a float issue because the motor cannot consume the entire contents of the gas chamber in one instance of a surge. This is a throttle issue.

Kohler Confidant 4 puts out to much voltage


Are you running the gen and plugging in the RV at the same time? I assume it is wired right and you have a transfer switch? Are you saying the voltage is fine when the RV isn't plugged in?

93 honda del sol will turn over but wont start. It has a new time belt, distrib, and the main relay works.


Is it not getting spark or gas? It needs both to run. Both main source. If no spark in any cylinder, then ignition module or crank sensor is likely faulty. If no gas, then fuel pressure regulator or fuel pump or fuel pump relay is bad.
