1983 f250 starting issues.
So I recently purchased my f250 and it was advertised as having a rebuilt 351w. So I thought I could grab it and do some work and have a pretty nice classic. Well come to find out this was a rebuild with a motor swap because the title says six cylinders instead if eight. The wiring job is shoddy and the day I got it the truck failed to rerun over with theed starter just spinning freely.
I changed the starter and the relay and lost power to everything after the work was done. found a blown fusable link thinking that was my problem. After mending that I hooked it back up and now when I turn my key to start the starter spins without engaging and when I turn it to off it still spins.

When the starter continues to spin, pull the red/light-blue wire off the solenoid... starter still spinning? If so, the solenoid (relay) is stuck; if not, most likely the ignition switch on the steering column needs attention.
There really isn't much to these systems...
The red/light-blue wire connects at 5, it supplies power to the electromagnet in the solenoid and tells it to connect the large connections (3 & 6) together.

I'll give that a shot in the morning but I also have two mystery wires and one of them seems to supply power to the fuse box and ignition switch(the blown fusable link). I also have a red wire with an inline fuse and I lose that one in a wiring harness after the firewall
Thanks for the fast reply and help.

I would guess the red wire with inline fuse is something some PO added, you'll have to trace that to figure out what it is.
Yes, I think there's a kinda-thick yellow (might be black.orange, I forget) with a fusible link that would supply power to the inside of the cab, don't expect anything to work if that fusible link is blown. More importantly, you need to find out why that thing has blown....

The fusable link looks factory but I can't tell the other write with the inline fuse. One is black and the other red with orange wire by the fuse were it looks to have been spliced in by the previous owner. Both have large eyelets that fit over the bigger studs.

Everything electrically is running as it should. I hear my solenoid click, and my starter is spinning. I was doing some research on it and it sounds like it could be the thrust bearing on the crank causing the flexplate to have slop in it? I had looked at the old starter and the wear marks on the teeth are on the outside of the gear for the starter. Could this possible be the problem

My personal suspicion is the guy installed the wrong flywheel/flexplate or the wrong starter motor. If there was enough thrust bearing slop to allow that much of a starter/flexplate mismatch, the engine would be noisy and would fly to pieces at moderate RPMs IMHO.
