I have a 6 volt generator on my jeep (42 GPW) marked EG-5001A . serial # 4wc12614. It is attached to a aftermarket voltage regulator with no markings other than "made in usa". Looks very much like your item # Item # 923131. 1. the current VR is not grounded by itself to the frame. Should it be grounded to the frame and if so would any mounting screw hole do? 2. Since it appears my system is an "A" system (from the A on the Generator), is Part # A1409 on this page compatible and does it require polarizing? Thanks Phil

Willys Jeep Parts Tech:
Please give us a call, we would be better able to answer all your questions by speaking with you.

Never replaced a voltage regulator before. Does this regulator need to be "polarized" when replacing the old regulator?

Willys Jeep Parts Tech:
Yes, typically that is the case.

Is this a A circuit voltage regulator that would work with a CJ-2a GDZ-4817A Generator? Thank you

Willys Jeep Parts Tech:
923131 or 923130 part numbers depending on voltage.

Hi; Would it work on an 6-volt 1944 Dodge WC-51 ? Thanks

Willys Jeep Parts Tech:
There is a good chance they would have used a similar one but we do not deal in Dodges to confirm.

Is the A1409 Voltage Regulator an Auto-Lite? WOF? Other? If it's a Auto-Lite is it a VRY4203A or B?

Willys Jeep Parts Tech:
Stamped on tag: REGULATOR S.B.P. VRY 4203A 6V 40A 9 61 01454

question. This product comes in 12 Volt. original body but 12V

Willys Jeep Parts Tech:
This comes in 6 volt only. We do have 12 volt regulators part number: 923130

I am working on the charging system on a 1945 Ford built Jeep GPW I have determined that I need a voltage regulator. The generator and starter have tags identifying them as 6 volt. The tag on regulator is missing. It has a 8 volt battery that the owner claims is stock to this Jeep Is that correct?

Willys Jeep Parts Tech:
Its an aftermarket battery but should work just fine. A lot of people do it.

The size is like the original piece? what it costs to ship to Italy? thanks

Willys Tech:
Yes these are just like the originals. We ship daily UPS and USPS international.

is this positive or negative ground

Willys Tech:
These are negative like original.
