6v Generator to 6v Alternator Conversion

[perrymedik]

Hi all!

 

I finally have some time back on my hands to work on getting the ol' girl (1949 Plymouth Special Deluxe P-18) running again.  

 

I have just purchased a 6v Alternator (1 wire) and mounting bracket from Quality Power.  I decided to keep it 6v because I didn't feel the need to upgrade to 12 and keeps everything as close to original as possible.

 

Aside from the alternator and bracket, do I need anything else?  Also, is there a good guide on how to wire it up (in the event it doesn't come with instructions)?

 

I am hoping that once I get this, the Carb, and fuel pump all re-installed, that I will be able to get her running and on the road again.

 

Any help, links, pictures or anything else would be appreciated.

 

ALSO!!  Talk to me like I don't know anything about what I'm doing, because I don't! LOL!

 

Thanks!

Cory;

I have one of these alternators installed. They work great. As long as your wiring is in good shape you should be good to go. Some people use the old voltage regulator as a terminal block for this but I went straight to the ammeter on my truck.

Say goodbye to charging issues.

Awesome!  Thanks for the info!

If you put in a 6v alternator does that change the ground?

Quality Power makes a 6V Positive unit that works very nicely.

I have the alternator now and installed! Woo Hoo!!

A few questions before I button that part up and move on to putting the rest back together:

The original Generator had two wires that went to the Voltage Regulator, a #10 Red and a #16 Green.  The Red went to the ARM terminal and the Green went to the FLD terminal.

When I installed the alternator (a 1 wire type), I ran the #10 Red wire from the Alternator to the ARM terminal.

1. Is this the correct setup?  

2. What do I do with the Green wire?

3. Will my Dashboard battery gauge still work?

Part of the info packet that came with the alternator shows the wire from the alternator going to the BAT terminal on my Voltage Regulator, but it also makes a point of noting that that is the set up for Negative Ground (and yes, I did make sure to purchase a 6v POS Ground Alternator).

Thanks in advance for the help!

There is a wire from the ammeter to the VR. You can run the single wire from the alternator directly to that same terminal on the VR. Disconnect the other wires to the VR. All it is doing now is serving as a terminal block.
