What motors in the T again???? Did you go for the sporty 302 or the classy flathead? lol

I'm sorry I couldn't resist

 

When I bought the car I bought the car, there was no option list as to the power plant as you well know.
The kicker is that when first built in the late 70`s the T had a FORD 428!

 

And yet the chevy lives in there... oh gotta give you a rough time.
The car still gives me a little wood even with a Chebby.

 

It would be so much sweeter with a Flattie or a 302/390 but I doubt it`ll ever happen, too many other projects, so little time.....

 

But actually what made my ming up to use a GM alternator (supposdly a high performance modiefed thing, I don't really care) is I saw a freshly rebuilt chrome one with a ready made attaching base for a Flathead motor.
Selling on Ebay for 85 bucks.

I just enjoy being a little sarcastic stinker

 

While the "one wire" alternators work they aren't an ideal setup. The "voltage sensing" wire is hooked directly to the alternators output terminal. So the only voltage that alternator is going to see is 14.4v and it doesn't know anything about the rest of the electrical system. So if you used a faulty or incorrect power wire to the battery, you could easily end up with a loss of 1V. Your battery is then only seeing 13.4v which is just enough to charge the battery and if further load is placed on that power by other accessories, the voltage loss increases further. At this point you are just running on the battery reserves and to the alternator it thinks everything is fine as it's sees 14.4v.

Now where the 2/3 wire alternators are better is, the "voltage sensing" wire is hooked directly to the main battery feed. So if we use the same scenario as above, the alternator will actually increase it's voltage output to compensate for the voltage loss and it also works in reverse. So if there is little load and you have a full battery is will decrease it's power output thus increasing alternator life and decreasing engine load.

The stock generator setup used 3 wires and wasn't a problem but an alternator can only have 1?

 

Hooray time for a debate! Maybe if yell out my contridiction everyone will think I'm smart too. Or I could shut up and keep the peace.

 

No debate please...
The 1 vs 3 wire makes sense that the 3 wire should be more accurate, I`ve heard that before.

 

please no debates...we know where that went last time... good info though...as always, my choice would be to stick with ford parts if its a ford truck...

Hows this rescource?

 

now that was totally un necessary!!

 

No one else saw the humor in it?

 

sure its funny, but won't be appreciated by much more than u and i...

 

I should really read what they modief in the system i got, think I got a manual.

But seriously the single wire system cleans up the motor bay alot, no more external regulator sure if your motor bay already has a mile of wire.....

Seriously I still find my last link funny I'm assuming Nathan didn't find the humor in it though....
