Starter staying engaged

[bayslayer]

Hello all, I have a 1987 ford F-250 with a 460 and the starter is staying engaged. My wife called me this morning and said she tried to start the truck and the starter wouldnt stop spinning. When I got home and put the battery cable back on the starter stayed engaged so I unplugged the ignition switch and the starter still spins with no key in. Could this be a bad ignition switch or should I look at the starter solenoid? Thanks in advance to any help.

Could be the ign switch, unhook the small wire from the starter solenoid. If it still does it the solenoid is stuck. If it stops you are getting power to the small wire, possibly a bad ign switch.
