I forgot to put that info in there didn't I.
2002 F150 Supercrew with the 4.6.
If it is just idoling it runs off the battery only. When a start from a stop or rev the engine the battery light goes off until it goes through each shift the more the battery light comes on then it just runs on the battery it's self.
I'll try to make it get the alternator checked.

The volts was like 12 or 13 something like that then this loop type deal that they put on there too was reading somewhere in the 34.
I changed the old battery out about 4 months ago and the post and the wires looked like they were almost brand new. I don't remember why I needed to change it but it did test bad.
I'll check over the wires the best I can.

Kev, it's pretty clear that your knowledge of the charging system is not at "expert" level. Trying to get valid advice out of us is like going to a blind man for his opinion on what we are looking at.
My (unexpert) advice is to take it to a reputable service center and make sure they guarantee their work. In reading all your posts, you've covered all the points I know about and if I were in your shoes, I'd 'punt". But, get the guarantee!

Myren and me want to know where you got the alternater from? And who checked it and said it was fine? Its a 2002 truck so I doubt it has wiring issue's unless someone's been doing electical work like new radio's or amps or after market lights or something along those lines. Might wanna check where your ground attach's to the engine and but sure its clean. My quess is you just got a bad alternater...........
