Voltage regulator smoking?

Good suggestions. These cars all pretty much had what is called a "fuse link" which is darn poor protection, but it may have finally blown.

Maybe you learned a lesson. At signs of trouble like this, stop and find out "whut." I know you don't know, but you could have disabled the charging system simply by pulling the "push on" connector off the VR or the green wire field connection at the alternator.

You have likely damaged some wiring. You are likely going to have to get into the dash, pull out the harness, unwrap them and examine for melt damage. it is common in such cases, for wiring to heat up and melt the insulation inside a harness and cross the wires inside together.

You are for sure going to need a factory service manual and wiring diagram
