Post serial # and you will get a more accurate response.
Did you just buy?I would be suspicious as to why the wires are all cut.

I had alot of starter issues and the first thing to verify is that the battery is charged. After that I used a multimeter to check for voltage drop at the battery, the battery side of the solenoid, the starter side of the solenoid and at the starter itself. The first time the brushes were gone, the second was a new starter where the ground broke of in the starter and the third time I had the ground go in my rebuilt original starter. On a seperate instance I had to replace the fuse. Hope this helps.
