The cost of many of these units is quite high, compared to what they used to be. Still, the choice of new, reman, or even one from a boneyard is your choice!
Consider that a new unit is just that.eEverything including the case is new. A remanufactured unit is "iffy" and depends upon the quality standards or the manufacturer... Some only replace failed items, clean it up and let it fly... Better shops, replace not only failed items but items which are slightly worn or prone to failure. (a good rebuild includes brushes, regulator, end bearings, diodes and anything else they deem necessary) When buying a "boneyard" part, try to get one with low miles, preferably one that looks as if it was recently replaced, or one that was in the latest year vehicle that fits your application. As I said the choice is yours!!!
Good luck!

SOURCE: no power to truck at all

If it's an automatic, and the engine doesn.t turn at all, the shifting lever may not be fully engaged in park,wiggle the shifting lever all the way up and down while turning the ignition,or put it in neutral and try it.check the starter solonoid, the pos.battery cable is connected to it.take a screw driver and jump the circuit from the where the cable is to the small wire going to the starter,it should crank over, if not the solonoid could be bad. check the small wire going to the starter.If you get back to me let me know if it's automatic or standard,6 or 8 cyl or no crank at all, or no start.

Your alternator went out and when the battery dropped too low the vehicle died. Without the alternator and no battery you have no power to run the electronics. Have the Alternator tested to find out if it is the alternator or the Voltage regulator and replace the bad one. Then recharge the battery and start the vehicle. It is possible you lost a Main Bus Fuse in the power distribution box or an in-line fuse on the positive wire but based on what you said it is the Alternator.
