Rebuilt generator to 12 volt source Hey guys I am looking for somebody that can rebuild my generator to 12 volts. The two shops I knew of in my area have closed. I am looking for just a internal conversion while leaving the original outside aged finish. Any recommendations?

Re: Rebuilt generator to 12 volt source Try Millworks Hot Rods&Supply Co, Tewksbury, MA 01876. They rebuild 1932-48 Ford generators for 12volts. Maybe someone can tell you someone closer. I haven't delt with this company directly. Be careful with conversions like this because the earlier generators can overheat if built to supply a lot of amps when wound for 12 volts. Also, you'll need a separate voltage regulator. Terry

Re: Rebuilt generator to 12 volt source Was hoping I would find somebody closer. I am in Michigan.

Re: Rebuilt generator to 12 volt source If you have a two brush 6v generator with a 6v voltage regulator, an early 12v regulator will sometimes do the job. 6v generators are quite capable of delivering 12v output without throwing solder if you don't have any 6v downstream accessories that might draw big amps on 12v.

Re: Rebuilt generator to 12 volt source Fairly easy to do yourself if your interested in trying it.

Re: Rebuilt generator to 12 volt source Itīs not a very good idee to just use a 12v regulator on a 6v generator...a fair chance to burn the field coil and relay..
2 fairly easy options for conversion available. 1: Buy a 12v field coil and a 12v relay this will give you around 75-80% output compared to a full 12v conversion works fine most times and the only thing you have to rebuild is installing the field coil in the casing of the generator. 2: Get hold of a 56- 12v generator and 12v relay, If you donīt need points correct you use the backplate casing and armature togetter with your original front and pulley. You will have to cut off 2 tabs from the back plate and if 48- drill the locating holes in the casing, this way you get an all ballbearing generator. Anyone with some wrenching skills can do the conversion. A heads up when swapping parts on generators...if you descide to use the entire housing with fields from the later generator with your old backplate and armature...there is a difference in length...and the locating notches is not in the same place...you assemble the pieces as is generator wonīt charge until you turn the backplate to a correct location against field in the casing. |

Here is Rumbleseat post: I don’t understand why flatheaders take their 6V generators to a rebuilder and have them converted to 12V. The charge is pretty high, usually around $100, when you consider only the generator fields have to be changed. The fields from a Falcon/Mustang/Comet bolt up in flathead generator cases. Like many things Ford did, there always seems to be an exception. If you’re using an original ‘39 or ‘40 generator, you will have to drill a hole in the case and install a grounded terminal for the new 12V field. Ford grounded these internally during ‘39-’40 and depended on the generator mounting for a ground. This new external ground terminal will replace the existing internal ground. These ‘39-’40 generators have only two external terminals instead of the usual three. I’ve been told 12V Falcon/Mustang/Comet complete generator cases will interchange with 6V flathead 8BA generator cases by simply grinding a locator pin slot in the 12V case, but I’ve not done any of these. It’s something to look at if you’re doing one of these change overs. A consideration: The armatures for a 12V Falcon/Mustang/Comet and a Ford 6V two brush generator are a one-way interchange because the 6V armature winding uses about twice the size wire as the 12V. The 6V armature works on 12V, but the 12V armature won’t work on 6V (the 12V armature wire size is too small for the current the 6V produces). Okay, okay..... there is one more thing when using a 6V armature in a 12V generator.... a 6V armature makes only about 75%-80% of the amperage the 12V armature does because there is one less commentator bar and winding in a 6V armature. I have a much more detailed writeup if I can find it! |

Re: Rebuilt generator to 12 volt source I got a 12V generator and regulator for my '51 Ford from Certified Auto Electric and has worked fine for a few years.
