Not that I recall, and I don"t see one in the wiring diagram.
But, there is a fusible Link. its a special wire that melts when too much current passes through it.
Its located at the starter solenoid, where the battery Positive cable attaches. There should be a smaller wire attached with it, that leads to your keyswitch, and to your voltage regulator. It may be covered in shrink tubing or black tape. The first 6 inches or so should be the fusible link. its often crimped or soldered to the wires that go to the key switch and voltage regulator.
This wire acts just like a fuse, and is special. you can"t just replace it with a regular piece of wire, if you expect it to provide fuse protection. If it melts though, you lose all power to the machine.
