Why won't my Kohler Portable Generator crank?
- A
  April BrockAug 9, 2025
  If your Kohler Portable Generator won't crank, the issue could stem from several causes: * A weak or dead battery: Recharge or replace the battery. Also, check the battery charger's operation. * Reversed or poor battery connections: Inspect the battery charging circuit, including the circuit breaker, module, and wiring (if equipped). * A blown fuse in the controller: Replace the fuse. * A defective starter or starter solenoid: Test their functionality. * A defective start/stop switch (master switch): Test its functionality. * The generator master switch is in the OFF position: Move the master switch to the AUTO position, especially when attempting start-up from a remote switch.
