sorry I first look at my 77. Follow the wire from terminal 1 it runs to a splice point to ground. Joel would this effect operation not 100 % sure of why the ground if not hooked up to a light bulb.

Joel I am missing something (easily confused) looking at your diagram B would be the heavy gauge wire Alt output, 2 is spliced to that wire for regulating out put voltage. 1 which on later models goes to the Gen light but on this year they have it going to ground. what am I missing?
And a
dual terminal connector. (Repair pig-tails for this connector available at any
auto parts store. Or, salvage with alternator if pulling the alternator from a
vehicle).
The #1 Terminal. (Marked with a 1 on the case)
This terminal is used to connect to the dash warning light.
For the warning light, a lamp is wired in series with a switched voltage
source. During normal operation the lamp stays off. If the regulator is
damaged, the #1 terminal provides ground, and the warning lamp will light.
Usually.
This terminal is also active on 1 wire regulator equipped 10SI alternators.
The #2 Terminal. (Marked with a 2 on the case)
This terminal is used to excite the 10SI into operation. (3-wire 10SI)
It is connected to the battery positive.
For simplicity you can connect the #2 connector pigtail directly to the batt
terminal on the alternator.

Found out that brown wire was my problem. Got it fixed with a new plug
