1993 Ford F-150 Starter and Alternator issues

Asked by GuruFR24Y May 01, 2020 at 11:59 PM about the 1993 Ford F-150 XL Stepside SB

Question type: Maintenance & Repair

My F-150 has a 4.9L straight 6 and I am having an alternator charging issue.
I replaced the OEM top plug on the alternator with direct connections and the
alternator started charging. Once it started charging the starter would remain
engaged and overheat. When I disconnect the power signal wire from
alternator the starter disengages but alternator will not charge battery.
I've gone through 2 alternators, 3 starters and 4 starter solenoids. I'm at my
wits end here, can someone tell me why this is happening?

Question, just so I am clear. Once you make the final connection of all related parts, the starter begins to spin (engaged) and remains that way, even with the key not turned to the start position? Check the starter solenoid.

Yes. Starter stays engaged. I replaced starter 3 times and the last one I got from parts store was tested Defoe I took it home.

Then power is being passed from the battery, to the starter at all times. If you have a fender mounted starter solenoid check using a test light or multi-meter if power is being supplied to the low voltage end from the ignition. It shouldn't be. Check the net for a video if you are uncertain how to check. If the solenoid is mounted on the starter itself, same procedure.
