Went out to help a new neighbor get up his leaves, but when I stopped the blades, couldn't get them going again. I had this problem before due to the battery not charging, at which point I replaced a bad voltage regulator. Today I tested the regulator by starting the engine and measured output with a multimeter and it was charging at 14+ volts.
I turned off the engine, but when I try to restart it, nothing. No cranking, no battery or oil lights, no power to anything. Yet the battery is fully charged. I've got the PTO switch turned off, depressed the brake (hydro's in neutral) and I'm sitting in the seat.
I checked the fuse and it's fine. What would you check next? PTO? Ignition?
