Craftsman Diode in PTO Harness

I have a Craftsman DYT4000 mower 917-273642. It was blowing the 20 amp fuse when I turned on the PTO. I have traced the problem to the diode in the PTO harness on the engine side. The diode melted and broke in half and burned off the insulation on the red wire from the PTO switch and caused a dead short. I need to replace the diode. What kind of diode do I need and where can I get one. Is there anything else I could do to fix this.

You can pick one up at radio shack. I don't know what part number it is. Take your old one if it still has legible info on it, or get one that is slightly bigger than yours and chances are it will be able to handle the current yours was made to handle.

A good replacement diode would be a 6A05. It's rated for 6 amps at 50vdc. It's only there to suppress the excessive voltage you get when you open/turn off a coil.

Depending on where you are in the state you could also hit Wayne Electronics in Wayne and Greenbrook Electronics in Greenbrook.
