I was told that the battery is overcharged. The battery and alternator tested good.
Even though the altenator tests good, it could still either over or undercharge.The TSB (Technical Service Bulletin) specifies replacing the alternator and re-flashing the PCM.(Powertrain Control Mudule).

When that light comes on, it is indicating charging system problem which could mean alternator not charging for one reason or another like loose belt, faulty alternator, or yes, bad battery or connection at battery, for example. First & easiest thing to do is check all your connections to battery, which you've probably done, and make sure they're tight & clean. Make sure belt driving alternator is good & tight, and in good shape. Now boost the vehicle to get it going & test voltage at battery, after you take cables off. My guess is in your case, the voltage will begin to go down, indicating a bad alternator, that will need to be replaced.

Sounds like part of a wiring harness is shorting to ground or breaking a ground connection. Check engine to frame ground straps and engine compartment wiring. Look for loose or broken leads esp. alternator and battery wires. Perhaps the power lead to the computer is faulty causing the truck to misfire. Any engine codes?

check your engine and battery ground wires and the fuze links.

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.
