SOURCE: kohler 12kw generator starts but shuts down after 3sec

Your gas pressure is too low and you may not have a large enough supply pipe. You need at least 10 inches of water column with the engine running to operate an LP vapor fueled engine. Because the engine is starving for fuel, its governor opens the throttle to WOT (so it goes to high revs) but there isn't any fuel to make horsepower with so the output voltage falls and the undervoltage alarm trips.

SOURCE: Hello, I have a Kohler Marine Generator that says OC on the menu when I try to start it. Any ideas?

OC stands for Over Crank. How long does it take before the genset starts?

Can't search for a manual without model, type, serial, etc numbers...

A few things to take a look at:

1) Oil level / pressure sending unit. This is normally bypassed as long as the start switch is pressed. When engine starts, and switch is released, engine will die if sending unit is defective, or you are low on oil.

2) Exhaust temperature sensors. Older units were notorious for burning these up.

3) Cooling Water Temperature sensor. These cause trouble often, but mostly due to water pump impeller being eaten away by galvanic action and not able to pump water as effecively. End result is water temp higher than normal, which trips the switch, which kills the engine.

4) Alternator (generator) output not as it should. If output doesn't rise to proper level within a few seconds of engine start, the engine will be shut down.

5) Choke not working as it should

6) Bad fuel, bad fuel pump, clogged fuel filter.

Make sure oil level is up to par. When it shuts down take the wire off the low oil switch and see if it runs.

I have a kohler 23eozd marine gen set thatwowouldn't crank. There's voltage 12.8vlts coming all the way to the sttarter but still wouldn't crank.


on the starter of the engine there are two teminals that should have 12volts to them while its cranking (or trying to) one has a 3/8 bolt stud and has a large wire/cable that should go to either the battery disconnect or direct to battery , the other one is 1/8" size and has a smaller wire to it , this is the trigger wire , it triggers the starter to operate , your going to need to look at those voltages when its trying to operate

Generator low voltage


It could be several things but it sounds like it just running too slow. I would the engine rpms first. Depending if is a two pole or four pole and if your 60hz or 50 Hz on the needed unloaded rpms.

Example: 2 pole 60 hz. Engine needs to be running at 3600 rpm loaded and 3750 rpm unloaded; unless, it has a fuel saving mode.
A 4 pole 60 hz would running half this rpm. The 2 pole producing 50hz would have the engine running at 3000 rpm loaded (about 3100 rpm unloaded)

Now in order for the 50 hz system to produce the same output voltage it requires a different alternator than the 60 hz version; otherwords, You simply can't convert a 60 hz to 50 hz version without changing the alternator by changing the engine speed.

I have a Kohler Marine 4ES Generator in my 29 Foot Sea Ray and the engine keeps cycling (no load) from almost shut-down to max speed. What can this be? I have changed the Electric Fuel Pump - Fuel...


The governor and / control maybe your issue. Also if you have the electronic governor model, check the speed sensor screwed in near the fly wheel, it should have approx 2VAC on it during crank.

I have a Kohler 12.5 KW marine generator on my houseboat that has a problem I was hoping you could help me with. Specs: Kohler 12.5 KW 79 CID 23HP Mfg date 9-10-96 Gen Engine Serial # 06919 L-29-R


there are some magnets behind the flywheel to cause the battery charging system to recharge the batt. sometimes they come unbonded/loose from the flywheel and cause the engine to become hard to turn. I would start there first.

My 20Kva Generac generator run for about 30 minutes and automaticly shut off. The alarm indicated that the generator has over speed. I don't know where to adjust or set the right hz.


The speed should be such that 60 Hz is generated when under load.

The govenor MAY be out of adjustment.

The speed for 60 Hz should be one of the following:

3600, 1800, 900 RPM
