What are the problems??
Not sure on that old of trucks, but the connectors might be different on the ones you buy at the autoparts store, have had that on cars too, just takes some splicing the old or finding a new/old connector and splicing it in. As far as alternator probs itself, take it to auto pts store and have them test chargin system. You can do it yourself, which would be 14ish volts whilst the truck is running. Measure at the battery with multitester, battery should be 12ish with truck off, all though there is parasitic drain from radio etc. You can also measure alternator at certain areas on alternator if it has open holes ot the coils.
Anywhoo, it could be a bad battery not holding a charge, it could be bad voltage regulator, it could be a bad pulley, it could be a worn belt. Also for better test is to take alternator out and take to auto parts store, but I have heard that they don't rev it up enough. The best battery test if have auto parts store do a "load' test. It test the battery's capacity to hold a charge, testing 12 volts generally doesn't say much about the battery but a load test will.
Hope you find the problem. Alternators are like water pumps, breaks and now with the plastic-metal radiators, they are like radiators, consumables. And they will go out over time.
