Alt question which post is which?

I am putting a 1275 in my bugeye. The 1275 is out of a 69 midget. The alt has two posts on the back of it. Which one is the b and which is the f? This is a Lucas alt that I imagine was either original or a replacement original at some time. I know it works as the car worked well before I took it out.

I'm not good with wiring and using a lot of info from here on it so I'm doing the alt swap right away.

TIA. Mike.

Re: Alt question which post is which?

The picture looks like a generator to me...
 
Yup, that is a generator and requires a regulator box.
 
The 1275s in '69 were still running generators. If yours has an alternator, then it was a conversion.
 
I think you are positive ground. If you are putting an alternator in you will probably have to reverse the ground to negative.
 
This is going to be a negative ground car. I spent this weekend tracing/replacing wires from the original harness in the car.

I think I am biting off too much at once for the initial swap. I am going to put in a genny and later on swap as recommended by someone on here in my other post.

Thanks for for the replies.
 
If the guys in the link below were in the U.S., I would consider the product suggested in the link below for a car that I wanted to keep looking "original".
https://www.dynamoregulatorconversions.com/about-me.php

On the Mini I made the alternator conversion and used a gutted control box as a junction box so the wiring is unaltered (making reverting back to a generator easy). There is also the very expensive Dynalite alternator built into the C40 generator body. Very nice and original looking but very expensive.
 
I did the same on my midget, Doug. The now empty RB 106 regulator box now contains the original and revised wiring diagram folded up inside a plastic baggy.
 
Oooh! I like that!

I never thought about storing anything in the empty regulator box. Since I'm not a smuggler maybe I should at least put something like a spare fuel filter or set of plugs in there.
