The voltage regulator type depends on which alternator you have (there are 2 different ones), on one the regulator is attached to the outside of the alternator and the other it is separate and mounted on the firewall I think. See pictures below so you can ID what you have.
1985 WOW ! does it run at all ? if it does , check battery voltage, should be between 12---14 volts, check alternator also, a parts store can do this for you ! is your regulator outside your alternator ? cause most new alternators have them inside the alternator ! just thinking out loud, but stranger things have happened ! are these new parts the correct ones for your make & model ? battery terminals clean, tight ! make sure all GROUNDS are good ! very important ! what condition are your battery cables ? is your BELT good, tight, not slipping !!! sure your starter & solonoid OK ! not shorting out, from dirt, grease, oil, etc., all fuses OK! I think we covered it, take your time, go over what I mentioned, see it you find the problem, good luck !
If you have access to a multimeter check the power terminal. It should be at least 13+ volts if the alternator is good while the car is running. The battery will not maintain more then generally 12 volts while the vehicle is off. Be careful not to drain the battery to far as it will damage it.
The mechanic should check if there is a loose wire that is not connected to the spare parts being said . then check the fuses if worn out or destroyed then replace them.Since it wont charge it means that there is a wire or fuses that are not connected or worn out.And proper connection should be done .Even though the spare parts are new but the connection is not in or according to the way it should be connected then it will not charge.
Why not eBay? you may be able to find a "lightly" used harness from an appropriate dodge or Chrysler product that uses your engines?
Try for a Repair manual or electrical repair segment for an appropriate Chrysler product with your engine.

Have you actually tested voltage output with multimeter, as this all happens ? May need new alternator to start with, it has voltage regulator built in I believe.
I had the same problemon my 87 model z. If you are looking at the front of the car THe battery Should be one the left. Just below the battery there is a little black box with some diferent colored wires in it. The one closest the the front of the car(SHOULD BE GREEN) is called a fusible link. You cant tell if its melted by the naked eye most likely, but if you pull on that wire i guarantee that its burnt. Touch the two burnt ends back together and vialah, everything cuts back on. Make sure your battery wasnt installed backwards. That was the reason mine blew.
