93 F-150 Electrical Issue
The Vehicle:
-1993 Ford F-150, 6L 4.9L, 5-Speed.
-Previous owner rebuilt the engine, replaced starter, replaced clutch, and installed an aftermarket LED light bar, klaxon horn, and radio.
The Problem:
-Driving the pickup, I suddenly began to lose power (both electrical and horsepower). Lights dimmed, engine sputtered. It was almost like I was running out of gas. After several minutes of this, the engine died and all lights went out. I jumped it, it started/ran fine, then died again in the same manner just minutes later.
My Response:
-I replaced the alternator brushes and got the battery checked out (AutoZone said it was "Good"). The problem and symptoms persisted so I bought a new alternator and installed it. The pickup ran without a problem for two days and then today it again sputtered, dimmed, and lost power before finally dying. Turning the key gives me "the click". The same symptoms as before.
My Suspicions:
-The aftermarket features are too great an energy drain and they are draining my battery faster than the alternator can charge it.
-There is some corrosion or poor connection in the wiring harness.
-The previous owner incorrectly installed the starter or went too cheap with the part and it is failing.

It would help us help you to see that info in your signature, as this caption explains:

Are you saying you bought the truck recently? How many miles/months between the PO's repairs & your current symptoms' first appearance?That's meaningless. The zone's goal is to separate you from as much money as possible for the crappiest parts available anywhere shoved across the counter by the people who are barely qualified to do that.Not surprising since you didn't diagnose them.That's the most-telling symptom. Click this & read all the captions:
(phone app link)Not likely. If it was, the alternator would be smoking-hot, and it would stink.That's very likely, as that link describes.The starter has nothing to do with the truck stalling while driving.
