I am also experiencing an intermittent no-crank when hot issue. I want to rule out the clutch safety switch. When I have the issue and I push the clutch in and turn the key to start I get a voltage drop. If I do not have the clutch in and I turn the key to start I get a slight voltage increase. Am I correct to conclude that the clutch switch is working because the voltage drop when the clutch is in is due to current being sent to the starter, and the voltage rise when the clutch is not in is due to the accessories being turned off, but no current going to the starter?
