'51 Ferguson TO30: Wiring Problems!!!

First off let me start by saying I am new to the forum and working on my first restoration project! :shock: :twisted:
I am restoring my Dad's 1951 Ferguson TO30 and have found through some diligent research the the Delco 10Si alternator is the preferred. Needless to say before doing the research I went out and purchased a Motrocraft 16 from the local AutoZone. I know with the Delco you have a BAT terminal and a P1 & P2 but, with the Motorcraft the Terminals are labeled; BAT, FLD, STA, GRD, and one has no label.
Does anyone have any experience with this type alternator or can point me in the right direction?

I have spoken with John...UK and he provided me with a wiring diagram but it is for the Delco alternator.

I have replaced the 12-Volt coil, Gear Shift Starter Switch, Battery, Battery Cables, New wiring (maybe that's my culprit), Starter, etc. and still can not get this -BLANK- to start!

Also do I need a regulator as the alternator has one internally?

Any help would be greatly appreciated!!!

The Alternator will have an internal regulator.
If you think that the wiring is to blame, run a wire from the positive terminal of the battery to the feed side of the coil, this will provide you with power for the ignition and if everything is OK it should start when you turn the engine.
The fact that the diagram was for a Delco Alternator I thought I explained the differences and just where to attach the wiring.
I think that you should go through the wiring one at a time and see that you have got the wires attached correctly. Being as you don't seem to have run the Engine yet, how do you know that the wiring is wrong...the fact that it wont start is nothing to do with the charging circuit and is completely separate. Try what I said above and by-pass the wiring and see if it will start then, it should do if you have the ignition side correct.....John(UK)...fergusontractors?hotmail.com

Don't know anything about that alternator. But normally an alternator with an internal regulator does NOT need a separate regulator. As Bob said, not charging and not starting are two entirely different things. If your battery is up, barring other issues, it should start even if alternator isn't hooked up. For alternator issues, try Googling Motorcraft 16 and see what you get. You could tell us what it does when you try to start it for possible answers on that portion of the question.

The alternator wiring should not stop the engine starting. Looks like you have two problems? I can't help with the alternator and need more details on the not starting.

Do you have spark at the points and plugs?
