Starter problems on a 1977 460 cid
I have a 1977 F250 Supercab 4x2 with a 460 cid automatic transmission. My problem is that the truck stopped starting. I replaced the ignition solenoid to no avail so I replaced the starter. This also did not fix the situation, the starter bench tested good. I was told that there should be a wire that goes from the ignition solenoid to the starter solenoid which is mounted on the starter. My question is from which terminals to run them from since the original starter never had this extra wire and worked. Yes the replacement was an exact match. Thanks in advance for your help

Need a description, ford starter solenoids on the older trucks were on the passenger side fender. If you have a solenoid on the starter then yes you will probably have to modify some wiring. The starter solenoid should have three wires. Battery to solenoid, solenoid to starter, and ignition to solenoid(small wire on face of solenoid.)

What kind of set-up do you have? I didn't know Ford ever had a starter with the solenoid mounted on the starter itself. In that case it would be considered a true solenoid, with the thing on the inner fender being a starter relay. Does your system resemble this diagram?

Diagramed description
The starter is an overrunning clutch design with a solenoid mounted on the starter motor. A starter relay is also installed on the passenger inner fender well. To the best of my knowledge this design was only used on the 1976-1977 460 cid engines, although the 6.9l diesel engine had a similar starter.

oops
I don't know where point #3 or #5 are but I did run a wire from the S treminal on the starter relay to the S treminal on the starter solenoid and it cranks and starts but runs really bad. The starter does not disengage but turning the key and holding it in the start position causes the engine to run smooth although the starter will not disengage. Didn't do this long as I know running the engine with the starter engaged is bad. ANy ideas?

sounds to me like you need a shim between the starter and the tranny housing where it bolts up I had a similar problem with my 460 when i installed the new engine. and it should be a wire from the battery to the solenoid and then from the other post to the starter and the small wire goes to the start terminal. the shim moves the starter so it doesnt stay engaged to the flywheel and will release.

What do we know?
If you put voltage to the "s" terminal, the engine will crank.
So we know the battery, starter relay and the starter are all good.
Apparently you are not getting voltage to the "s" terminal when you turn the keyswitch all the way to start. There are several possiblities why this is not getting voltage:
The ignition switch is bad.
The linkage to the ignition switch is bad(if your keyswitch is on the column)
The park/neutral start switch is bad(clutch switch on a manual tranny)

Still doesn't work
undefinedI replaced the ignition switch and have checked the neutral safety switch. I will now have to check each wire from under the dash out to try to find if the problem is in the wires
