If you have a new alternator its as simple as run the one wire to the solenoid. If you are converting the alternator to a one wire, you will need an external regulator.

if you replace the alternator will you also be replacing the voltage regulator
On a dodge alternator the two small wires go to the voltage regulator . It doesn't matter which wire goes where, but the red or blue wire needs 12 volts when the key is on. The green wire goes directly to the regulator from the alternator. The large wire goes to the battery and it is important that you don't undersize this wire. The other wire is a ground wire and can be grounded to the block or not used as the case is grounded by the bolts that hold it on.
Voltage regulator or loose wire.
The regulator is not making a good ground to fender/firewall, or there is a good chance of broken wire between Regulator and Alternator. there is either 2 or 3 wires between them and possibly were mixed up, should be Field, Stator, and or Bat, allso some Alternators have ground wire be sure its in the right place or you may blow your new Regulator
A one wire alternator has one wire that sends electricity to the battery and electrical system. They usually always have an internal regulator.
If it has an external regulator. The orange wire comes out of the alternator, then is spiced-"T"- into another wire which still should be orange going to the regulator plug, and the other wire coming from the "T" should be an orange wire with a tracer that goes to the "no charge" light on the dash. The other wire coming from the light goes to the ignition switch.
What Type of alternator do you have? I can't believe the people that don't state make, model, year and engine size before posting a question.
Im not sure if your talking Alternator output wire fuseable link or regulator exciter wire, i would assume your talking the exciter wire, it may have a short and is grounding out on the engine or frame somewhere
Assuming you mean the voltage regulator. Chrysler products of that era used the "One wire system". The voltage regulator is integral to the alternator.
There should be a heavy wire called the Alternator output wire, It carries power from the alternator to power your accessories and to maintain your battery. The smaller wires usually in a plug are either the alternator's voltage sense, Stator/ACurrent/Tachometer output, regulator/indicator light. or if its an Externaly regulated alternator they will be alternator Field, Stator/ACurrent/Tachometer. hope this helps
voltage regulator.
