Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello. Thank you for choosing Just Answer. My name is***** will be happy to assist you.
I would like to confirm something.
Are you saying that your fuse blows, after you turn your pto switch to on position? Your engine will start up and run, but your fuse blows, as you are attempting to turn on your pto switch?
There is a diode in the wire going to your pto clutch. I am referring to the wire that provides 12 volt to your pto clutch. If your diode is bad, this could be the source of our problem. Check your diode first , then we can continue from here. Thanks again!
