What to do if my Kohler Portable Generator will not start but cranks okay?
If your Kohler Portable Generator's engine cranks but doesn't start, ensure there's fuel in the tank. If the tank is full, the fuel pump may be defective and needs replacement. Note that the fuel pump is polarity sensitive and will fail if the lead connections are made in reverse.
How to fix a Kohler 15CCO that will not crank (dead)?
If your Kohler Portable Generator's engine won't crank, start by checking the 10-amp supply fuse in the controller and replace it if blown. If the fuse continues to fail, replace it again and then troubleshoot the DC circuit and wiring. Also, check the battery connections to ensure they are properly connected.
What to do if Kohler 15CCO Portable Generator engine starts, but stops after start switch is released?
If your Kohler Portable Generator starts but stops when you release the start switch, begin by checking the AC output voltage. Also, check the continuity of the wiring at the P1 or P2 connector. Additionally, the K1 relay coil might be defective and need a continuity check.
Why Kohler 15CCO will not start (cranks okay) (continued)?
If your Kohler Portable Generator still will not start after cranking, the battery may be weak or dead. Recharge the battery, check the electrolyte level and specific gravity if your battery has filler caps, and perform a load test. If necessary, replace the battery.
