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.

Kohler 12.5 res gen. Battery is good. Get OC code. If I reset auto switch by clicking off, then clicking run, then clicking auto it will start. Any thoughts on this issue?


OC is Over Crank which generally means it cranked and cranked and failed to start. Turning the switch off and on again is the way to clear the fault. How long is it taking to start whilst cranking? It should start within 8 seconds

No 110 ac power out of gem


Check the rotor slip rings for tarnish as it has sat.
If they are clean, the rotor may have lost it's magnetism and may need flashing (putting DC power directly on it for approx 3 seconds) with brush wires disconencted POLARITY IS CRITICAL

My gen starts and runs for 1 min or so then dies restarts then dies again and again. if i start it under load ( turn on air con) it will run for 10 min then die allen


Is there a fault?? All UL listed generators including Kohler are required to lockout on a fault on shut down. This really sounds like a problem with your 2-wire auto start connection between your automatic transfer switch and genset. RDT model automatic transfer switch it is the 2 middle wires on the green connector and terminals 3&4 in the generator. close to run and open to shut down. Any open at any time will cause the unit to shut down. The 12 will shut down instantly upon an open because your 5 minute cool down is built into the transfer switch.

1975, 7.5 Kohler marine genset, runs only with the reset depresed


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.
