Terminals on my Alternator

Corey Allison · Mar 30, 2011

I just bought a conversion kit from Ytractor and theres the two terminal slots and was want to know if some one could tell me how and where to hook these wires up, i dont want to try to turn over the tractor until i get this solved. The conversion kit is on a 1950 ford tractor.

Does the kit use a Delco SI type alternator ?
If so, is the alternator a "one wire" self exciting type ? If it is the "one wire" type, nothing gois on the regulator terminals.

If the alternator is a 3 wire type, then this link shows where the wires go.

hey alternator has only 1 hot bat. post and a ground, then there's the 2" terminal spots with a plug in it

That is a simple one wire. You have to have the battery - ground and the ground on the alternator is - and the big post goes to the hot side of the solenoid. But I would think that kit came with a wiring diagram

AH.. NO.. not a one wire if it has the "plug" w/ 2 wires on top. "One Wire" units usually have that slot "plugged" with what seems to be a non removable plug and no wires.. or at least the last 2 I got from NAPA sure did

But I suppose he could wire it up such as a 1 wire and find out it still won't charge I guess.

ya i got everyone almost wired up i just didnt know what to do with the terminal slot on the alternator, I wanted to ask before i started the tractor and messed something up

As a matter of fact the only wire that really need to be hooked up is the one from the big post. The alternator will ground on its own by way of the case. That is why it is termed one wire and only need a single wire going to the hot side of the solenoid to work

While im here will the Voltage Regulator work that came on the tractor in 1950 with this new wiring kit that i added. i looked around and could not find a wiring diagram for that on which wire goes where???

Sorry Rich, in the post, it says the 2 other terminals.. BUT I just done some homework, and it appears if he bought the kit from YT (which if I read correctly that is where he got it).. And it should be self exciting, so the 2 wires would not be used.

HOWEVER I've mounted a few delco's in the last couple years, and I'll tell ya, unless the alternator is set up as Self-Exciting IT WILL NOT charge.. One of the 2 posts on top is excite post, the other is supposed to be what I believe they call a "stabilization post" (tells the internal regulator what the charge status on the battery is.. or is how it was explained to me.).

I will agree that a external ground wire is USUALLY not required..

So Rich, I guess, in conclusion, we're both right.. In self exciting, you are correct.. But had it not been self exciting, the other posts would be needed.. Still is strange that those posts are not "blocked off" though, as the 1-wire I have has them blocked.

That alternator has a built in VR you just remove that old one and set it in a box or throw it away etc it is not and can not be used with the alternator. Oh by the way is that a 8N front or side mount distributor since in 1950 if an early one would be a front and a late 50 a side mount

Ya I had to sort of get answers to know 100% sure what he was asking but he slowly filled in the blanks. I still have one tractor with a 1 wire alternator and I love to hate that alternator. One time it will charge just fine then the next time it will not. Funny thing is that it is on of all things a 1950 Ford 8N with a back hoe
