White STA alternator wire question?
Where the heck does it go? Is it switched? Is it a positive feed?
On the donor 79 truck it dissapears into the wire harness... in the 67 it's gone into it didn't have this wire ( or at least not this color and I have no idea what to hook it to. )
The Bat wire is self explanitory and the field wire(s) go to the regulator to be switched.
Help

Hmm that is not the diagram I was working from..but it looks good. I will re check it when i get back to the shop tomorrow. So in other words it has nothing to do with alternator charge at all...

It does matter if you have an alternator light in the dash(the lower diagram).
If the truck you are swapping it into has the light in the dash, then you need to use the lower diagram, and it's harness that uses the "i" terminal. If you try to use the ammeter harness(top diagram) with a truck that has the light in the dash, it won't work right.

It's a 67 F250... with Ammeter... there was a large yellow wire to the reg, a large black wire to hot side of solonoid... another wire from reg to hot side of solonoid ( think now that should have gone to the I terminal..oops)..not that it's a huge deal I guess long as it's a positive feed.
I just had no idea what used to happen with the white wire( was different color on my 67 anyways I think it was green).. as the white I cut with a chunk of the 73-79 harness, dissapears into the wire harness( I guess donor truck had light not guage).. I was just wondering if I needed to hook that wire to anything. I have just swapped a Holley Avenger 670 carb on so I could now run that white wire to the carb I guess...
