Shut off with mower & transmission in gear. When went to start it, there was no power or sound. Not even a click. I put it in neutral, and disengaged the deck, and depressed the clutch. No results. The battery is fine; the fuse is fine. It's hard to get at electrical switch & solenoid (beneath gas tank in front of panel) to test if power is going to them. I'm wondering if the problem is the safety switches -- being shut off in gear & deck engaged. Any suggestions.
