Wise words there and something that you really need to check before spending any more money.
Check the alternator out and see if it is working right or capable of working right before changing it out.
Is the plug going to the regulator hooked up and is it hooked up correctly?
Is there a specific reason you changed the regulator?
About the only thing that normally goes wrong with the external regulator alternators is that the brushes wear out and don't make good contact with the rings on the rotor. If you short something out on the truck you might blow a diode. Also once in a while a stator will fail but I think that is primarily due to over charging. And the bearings will make noise after a while but they are easy to change too.
