how old is the battery it could have a bad cell that would cause this problem

SOURCE: Battery dosn't charge, alternator/voltage adapter test's good.

Did you test the Alternator on or off the truck? It might be a problem with the control system to the Alternator. The regulator need a battery feed to work, It is usually ran through an alternator fuse.

on the field wires ones a posative and one a negative and the single post gets connected to a wire that runs straight to the main fuse box in the engine compartment then is fused to another wire that goes to the battery have that fuse checked it could be your problem as far as the feild wires the positive side only works when you start the vehicle up to engage the field

If the condition is present for short times only it will not affect anything. It's possible that the crank pulley is glazed and slipping slightly on a hard pull (everything else depends upon that pulley to be properly driven) You can't really duplicate that on a static test. It's also possible that the battery was a bit low when you bought it and needs to have the charge level topped off with an external charger. Otherwise, the only option I can think of offhand would be to obtain an alternator designed for heavy duty service (police version etc) which may be able to deal with the demand.
As your vehicle gets older, resistance in all circuits increases, making little difference during normal operation but can also influence how your vehicle charges. Cleaning / adding additional ground points can help with this.
If it seems that I'm jumping around a bit, I am, but since the charging system is pretty much operational except at that one point, I'm trying to give you some ideas that either in combination, or one alone will be of some help to you.
good luck
