OK I have a AYP 22hp kohler with a electric pto clutch. The engine won't turn over with the key switch . I can jump the key switch and it will run. It will stay running as long as I leave the clutch/brake pedal engaged. If I release the clutch or try to engage the blades it will die . At first I thought I Had a bad seat safety switch but I can jump that and it still shuts off. Please help!

Sounds like the key switch needs replacing... try that first. (some of the contacts inside are NOT contacting)

Thanks I was thinking that but wasn't really sure . I will try that first

I replaced 4 terminal solenoid, swapped batt! I get 12v at solenoid when turn key! Seem to have bad, or no ground at solenoid!
