SI alternator wiring question on 74
Gentlemen,
Im having a hard time deciphering wiring diagrams. I am working on the voltage regulator two prong connector on the alternator and the main power-up wire to the dash.
Question 1. My Limited Lectric wiring diagram for 74 seems to be missing the brown wire that connects to the #1 pin (field) on the alternator (pen point to finger tip). Where does that wire actually go? What does it do?
Question 2. This diagram kinda shows what I have now. I am trying to clean up the "nasty splice". I added a red line in to show the current #2 (sensing) wire that attaches to a splice between the junction block and the dash power wire.
What would happen if I ran the #2 sensing wire to the junction block, instead of that splice into the main power up wire? (dash line)
Thank you,
John

I got Mark from MADelectrical.com on the phone and he recommend to go ahead and delete the splice and run the main power and fusible link to the terminal block and a separate wire from the voltage sensing pin on the alternator to the terminal block.

Think of it as a switch that "turns the alternator on"

Interesting that the wire is missing from the harness - perhaps ordered for a "1 wire" alternator (I have no idea if Lectric Limited offers that - or assumes it!!)
