Autolite Regulator Question
#1

I want to replace the regulator in my '39 Six 1700. I came up with one online that is NOS, looks to be in excellent condition and says it is correct for '37-'39 Junior cars. It is a VRR-4002B. The seller says Tuscon Packard told him this was 'spec-correct' for 37-39 Junior cars. When I check on the Packard parts site, it looks to me like they say a VRD-4001A or a VRD-4005A is the correct number for a '39 1700. Knowing how much these numbers can get switched up over the years, can anybody help me with this?? For what it's worth, the NOS unit on Ebay doesn't look like the one in my car, but I have no way of knowing if mine is original or has been 'crossed' with another model. Pictures below; first one is what mine 'looks' like, 2nd is Ebay offering. Thanks to any help or input anyone can offer up.

VRR 4002B is for a 1939 Studebaker Champion. The only other users of the VRR-series that I'm aware of are Hudson, Hupmobile, and Willys although only Studebaker used that specific 4002B unit. The Studebaker was 6-volt and positive ground.

Motor's Manual indicates that a VRD 4001B is also applicable to the '39 Packard Six.

The second, smaller unit is the correct type and all but the super critical will not notice that the exact model # is incorrect. It will work just fine, remember to polarize upon installation.

Thanks J from Kanters. Is there a polarization 'how-to' guide anywhere on our site??

Much appreciate your help!
Best Chris

Everything connected, key off then do the polarizing. Use a decent size wire 14ga or so and just touch the terminals together. There will be a small spark as the connection is made and jumper only needs to be held for a second or two.
