Lots of work on Brad's part ... pure enjoyment (and references) for you!

Now going to work in the morning I am now noticing no charge at the ammeter and as I am stopping at a light the head lights are almost going out. Now hopefully when I polarized the regulator with the engine running I run a wire from the Bat. on the regulator to the arm. real quick maybe 2 seconds. The parts guy said the engine should have not been running when I polarized the regulator just like when you do a generator. I also took the cover off the regulator, started the engine and there is some fire works going on under the field points which does not look normal, maybe an adjusment? No savy need a little bailout here Bolters thank you....

You do not polarize a regulator. You polarize the gen. when ever service work is done on the system. Hook a voltmeter to the bat. term. & rev it up a little. It should read about 14 volts.

You need to make some voltage and current measurements, with accurate instruments. The dash ammeter is about as accurate as finding "north" by checking which side the moss growing on the trees!

The binding is falling apart, and I've been intending to transfer it to loose leaf form with plastic document protectors to prevent any further deterioration. Drop me a PM or an email (in my profile) and I'll be glad to try to give you a quick tutorial on how to do the circuit testing and diagnosis that's needed to determine what's going wrong, and how to correct it. I believe I was probably among the last generation of mechanics who trained on DC generator/regulator systems, and made our living working on them, back in the late 1950's and early 60's.
