Delco 27MT starter I assume. You need to ascertain if the plunger inside the solenoid is sticking . . . or if the contacts in the solenoid cap are pitted and sticking . . . or if the voltage going to the solenoid "S" terminal isn't being cut off. When you turn the key and power gets to the "S" terminal - an electromagnet pulls a metal plunger against a spring that pushes against a rocker-arm that puts the starter drive into the proper place. Once pushed all the way a button is pushed in that makes the copper contacts close and make the armature spin. The starter drive has no "Bendix." It uses a sprag roller clutch that acts like a one-way rachet. As another poster mentioned - if the starter drive gets stuck "engaged" - it prevents a sort of "back-feed" and keeps the power going even if the power is shut off to the solenoid. Delco direct-drive starters have a pretty weak drive-stop at the end of the armature that come off at times. So - your problem can be stuck contacts, sticking plunger, broken drive stop, etc.
