Looking for a troubleshooting guide for Kohler 7.3 ECD Marine generator
Posted by Anonymous on
I have a kohler marine generator that shuts down when it reaches operating temp of 200/210 degrees. It runs for about 5 minutes. Already replaced impella and have sea water pumping through, coolant level is good. Any suggestions? Thanks

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

The pickup tube in the craft's fuel tank has likely worked loose and dropped into the tank. The generator lost its "straw" that it needs to siphon fuel through.

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.

Double check your grounds at both the frame and the battery. Otherwise, your starter probably has a shorted field.
