Packard Forum Index » V-8 (1955-56)

My son and I recently partnered in a 56 Patrician. It does not seem to charge properly even though the regulator looks like it is a fairly new Borg Warner. He is a mechanic and his test point to the regulator. ( he has polarized) Does anyone have a make and model number for this 1 year only negative ground 12 volt unit that I can try to find? Appreciate the help.

The 56 Patrician should use the Delco regulator and generator but just in case something was swapped over the years here are the original numbers for both Delco and Auto-Lite. I would not be surprised if other cars of the era used the same.

When I needed a new regulator for my '56 with Delco equipment, I just went to NAPA for their aftermarket replacement equivalent to the original Delco. It's been working just fine for quite some time now, and it's still available at NAPA. And it's not a 1-year only unit (though it was for Packard). I don't if it is still available under the same part number or if it has been superceded, but it was NAPA/Echlin VR 122.

That is a big help. Thanks, TOmmy

Thanks, I am going to take the number you gave and the one Howard gave to my nearest NAPA store. Tommy

if that does not do it,

I went alternator route,

Is your Packard a 55 or a 56?

The 55 were positive ground, the 56 changed to negative ground.
