65 Barracuda daily driver

Thanks for your help as always! Now I have put a wire through the bulkhead connector. The connector had stripped threads and couldn't provide a good connection. I also added the 2 wires with fuses from the alternator to the battery as mentioned above. Then I double checked everything and started the car. I had the fire extinguisher ready - just in case... Everything seemed fine. I had read something about overcharging and so I went ahead and check the voltage at the battery. 17-18 volts!!! Luckily I still had a spare voltage regulator somewhere. Not new, but good enough to test if something would change. It did, and now it's at around the voltage at battery at idle is 15 volts. Still on the higher side as I read, but certainly an improvement. I should get new one - are they all the same or are they specific to the alternator or something? Anyhow, I haven't test driven the car yet, but I will do that right now. Fingers crossed that this solved the issues that I've been having.
