HELP ASAP!!!!!!!!!!!!!!!!!!!!
im about to shove this truck off a cliff (however with my luck it would drive itself back to me) i have a 91 half ton with the 300 and 4 on the floor, recently i took out my dash to do a giant clean up job, i put everthing back together as i found it, about 36 hours later the headlights were getting dim and the truck was running odd, i determined it must be the alternator, so i took it in to have it tested, it tested at 9 volts (clearly not enough) got a new alternator, problems persist!!!!!!!!!!!!!!! help!!!!!!!!!!!! i checked all the alternator wiringthe truck stays at about 12.6 volts and idles/runs on about 12.4..... help me, the baterry slowly drains and ... ugh i just wanna run this thing off a cliff

Check the wiring pigtail just behind the headlamp switch, and check the wiring pigtail at the alternator especially the one at the alt. as they actually reccomend replacing that harness (Major shorting issues that actually created fires) when changing an alt during that generation Ford truck....
