Ford regulator on VW alternator? It works!!!

headhunter14

im having trouble grasping this. I have a 69 bug that came with a generator. I swapped the motor and it comes with a alternator with the 3 prong plug for the ext. regulator. So i buy the late model ford VR. I hooked it up in reference with the yellow sticky note, the problem im having is if i run the wire coming from the fuse box to the "A" terminal i dont have any power. if i piggy back the the "A" terminal with the positive battery post i have power but it dosent charge. i guess i, just confused.

The Standard VR-124 or the Duralast VR-650 AutoZone.Com should also work and match the VW wire colors on the Motorola 8AL series Alternator.

You do realize that most Pintos had Weber derived carburetors that will fit a wide range of cars including many Fiats, Alfas, Lada, and even other American cars like Vegas.

I bet you think that your VW has a German carburetor. Even if it's an original Solex, it's French.

It might be helpful to someone who might need this in the future if someone said which Ford regulator to buy!

After all, you can't just walk into a store and say gimme "the inexpensive old style Ford external regulator".

Maybe a part # and a pic?

I know that my diagram is generic, but if you use the power wire going to the coil for the "A" connection on the regulator, then the only wire leaving the engine compartment is the "I" connection, on the regulator. going to the Negative side of your idiot light.

Next thing you know, you'll be wanting to run a Ford Pinto carburetor as well...

Ford regulator. I just did this. It works great!

Amazon sells those for roughly $30, and the cheapest on ebay was around $20, the Ford Regulators have been around for a long time, you can still get American made ones so you don't have to buy chinese, and they are always cheap and can be had at almost any parts store.

Yours does however provide another source, and you can never have too many.

When you get one of these alternators like I did out of a 1974 Beetle it's always a worry that you can figure it out and find a regulator that will work for it. I sent off for one like the VR-124, The colors match to the vw Colors when wiring it up!

VR-124 With Matching VW Wire Colors.
Standard Brand VR-124.

I found one on e-bay for like $15. which worked fine but it was a Wells VR-650. Looks like the same part.
The regulator gets it power from D+ on it's Red wire and supplies DF (green wire)which is the brush that is not connected to ground. D- needed to be grounded (brown wire) on mine as it floats when the brushes are well centered. The voltage regulator had no problem providing the 5 to 7 volts needed on the 5 ohm armature of the old Motorola VW Beetle Alternator. The Dash light in my 71 Bus works as excitation but it measured about 16 ohms it could be lower. But it all works fine. The Alt Dash indicator lamp also connects to D+. Just like in the schematic!
Regulator from Auto Zone.

Good to hear, I'll get to work on a nice color coded wiring diagram for everyone soon, I knew it would work, was just a matter of testing out which way to wire it, my baja didn't come with a reg when I bought it, and has the Bosch 55amp external reg alt, first thing that came to mind was the Ford regulator. $15 vs way too much, no brainer!

I tested an alternative wiring that also works. Rather than hooking the idiot light to D+, you can instead hook it up to the regulators I terminal, and it also works.

So basically Rich,s right hand diagram works. Couldn't get any charge without an idiot light to start the process.

It works.

Here is the wiring:

Ford regulator

I Disconnected or idiot light (rather than D +)
A. Key on positive , such as ignition
S To D + on alternator and idiot light to positive key on
F. To DF

Alternator

D- To ground
DF. To F on ford regulator
D+. To S on ford regulator and through the idiot light to key on positive if you didn't hook a light up to the regs I terminal.
