Re: generator to altenator conversion?

Hi ShortyCox, I sure hope you're still watching this thread...

First off, thank you for providing this directions several times on this site as well as others. However...

I have a few issues with your instructions:
Step 2: my voltage regulator has 3 connections (not 4)
Step 3: I can't test any of my wires for a "hot" one since I've already swapped out the generator for the alternator (all my wires are loose)
Step 4: what is the regulator position, and the generator/alternator position? This is confusing.
Step 7: again, what is the regulator position?
Step 9: wires to my generator are x2 thick, x1 thin (not x1 thick, x2 thin)

Also, from the steps you provided, it looks like the horn relay might be disabled? Hard to tell, since I haven't completed your steps and your steps are confusing.

I have a 1962 C20. I just swapped out the old front harness with a new one from classicparts.com. The thick/thin wires and colored wires are nearly identical (this means there's really no confusion on my end because of the new harness). My dash uses the idiot/telltale light. My new alternator is a 12SI.

Other things that add to my confusion:
- I don't know what "ARM" and "FIELD" means, or their intended purpose (I might be able to figure out some of your directions if I did)
- My voltage regulator tabs were not labeled, so I don't know which wire does what-
- One of the wires to my generator is clearly a ground wire, but none of the directions I have found so far even mention a ground wire, much less what to do with it.
- All directions either reference wire color (which is never the same as mine), or provides vague reference to "this wire" or "that wire".

I'm sure I'm missing the obvious, so I would really appreciate some updated help here.

Thank you!
