I have a B1750 that I started , raised the bucket and let the clutch out. It stalled and lost all dash lights. Would not crank or start. No power. Here's what I have done. Tested battery, checked battery connections, cleaned terminals, removed negative cable and cleaned. Checked the fuseable link. There is 12v at the starter solenoid. Replaced ignition switch. Any thoughts? I'm running out of ideas.
