Troubleshooting

For example, a starting problem could be caused by an empty fuel tank. Some common causes of engine troubles
are listed in the following table.
Do not attempt to service or replace major engine components, or any items that require special timing or
adjustment procedures. Have your Kohler Engine Service Center do this work.

Engine key switch can not draw more than 2-amps.
A relay may be used in order to use a higher drawing
accessory. Contact a Kohler Engines application
specialist for further instructions. A current draw of
more than 2-amps will cause damage to the ECU, Fuel
Pump Module, or other electrical system components
and will void the warranty.
