First, charge and check the battery. If you drove it home, maybe you just made it in the battery. Maybe the “jump” was enough to get you to the garage. Seems unlikely though.

If properly converted a resistor would have been added on the coil wire, and it’s only seeing 6 or so volts running. (This ignores the bypass for start up, another item).

A 1 wire alternator hook up is ok. But if it’s a GM, there should be a jumper between the “other” 2 connections. That also gets into another area.

Give us a little more info. Starts, drives good, shifts, sounds like a great start (pardon the pun).
