May I suggest that you drive your car to one of the major auto stores and they can and will check your alternator for you to make sure it is good/bad.These places like AutoZone do this all the time. They do not charge for the check out. (Of course they are hoping that if you need a part you will buy it from them.
One other suggestion. If you do need a new alternator, get a rebuilt one. It is cheaper and most always comes with a warranty.
Hope this helps Good luck Loringh PS please take a moment to give me a rating

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.

SOURCE: Instrument panel went dead
Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).
