Hello, I need help figuring out a problem
Starter relay periodically burns out and 15 amp fuse shows visible signs of being hot but not blown
Any ideas if this is a common problem and what's causing it
What you are explaining sounds typical of an abnormal draw on the electrical system. Somewhere there is more power being drawn through the fuse/circuit than what should be. You could use a digital multi-meter to see what the current is through the key switch or through the fuse or through the relay. I am not sure what this will tell you but you can report back and maybe someone will know if something looks put of the ordinary.
I have checked wiring out down to clutch. Don't see any frays, breaks, or shorts. Could the clutch cause an overload even though it's functioning?

In no way is the starter/solenoid connected to the PTO. If the PTO is feeding back to either the ignition switch would be the problem, even though I have never heard of this happening.

Is this symptom showing up immediately after shutting off the pto. And when you said starter relay are we talking the starter solenoid or a separate little square box relay that energizes the starter solenoid. If it is the starter solenoid, may want to check for stray voltage getting to the starter solenoid when the engine is running. Like the key switch is sending some power to the starter solenoid causing then engagement coil to burn out.
