My Kohler 15.5EOZD Generator (@10 yrs old) won't crank at all. Displays CC1 (hearing fuel pump start) then nothing. After the display reads OC . In other words, it does not even try to do a second crank cycle.


On the last use 2 weeks ago it worked great and shut down as per normal. I assumed this was a battery issue as the bank was 5-1/4 years old so I went ahead and changed the batteries - same issue. Checked the three fuses on harness- all fine.

Starter is on back of generator- against a bulk-head - so testing this is a bit tricky.

Any other preliminary checks i should make?
