I'm in the process of restoring my '52 8N. It currently has a sloppy 6 to 12 volt conversion using an alternator. I would like to restore to the original look but would also like a 12 volt system. I read that it is possible for a shop to convert a 6 volt generator to a 12 volt. Is it feasible? Would I then be able to use an orginal type wiring harness? Are there any negatives? Thanks.

Me and a Guy in GA have been working on a stealth, and have had some success with limits. The late 8N 12V Generator I built him would work, but not below 1700 RPM if I remember right, and based on how the thing lined up with the crank pulley, my 5/8" Delco alt pulleys would not fit his application. The early 8s as well as 9Ns and 2Ns can be done (if you use the early 8N generator) with a smaller pulley so it revs the generator higher. i'm in the process of putting one on my 1941 9N. (BTW, I still have NO IDEA how to put tension on this generator, anybody help please? ) I need to get the C0NF10505 VREG next time i'm near a NH Dealer. i've said before, i'm not a purist, but enjoy a little vintage 'style' from time to time. I did manage to put one of those under $10 ammeters in yesterday, and I'm a little closer to my goal. I only work on the sucker once a week at best between work, wife, kids, school, city council, etc. Good luck whichever way you go, and find an OLD rebuilder in your town. Hey Dell, have you heard of the falcon VREG/GEN working on these in the past? I wasn't sure if the RPMs might not be an issue. I have the fields in my GEN wired in parallel instead of series for higher magnetic output.
Have a good night all

Rick..... ....most 12 volt conversions use the Delco 10-SI alternator with built-in voltage regulater because they are "cheap".

But if you want a "stealth" 12 volt conversion, go shopping. Yes, you can have the gutts to a N-Generator changed to 12 volt field coils. Then you need a compattable voltage regulator. Not cheap conversion.

Check out a 1960's Ford Falcoln 12 volt generator + external 12 volt regulator. You're on your own for such conversions, you better well understand automotive electrical systems..... .....Dell

Hi guys,

I happened by an antique car show yesterday, and stopped in. The had a nice selection of late 20's ford trucks, and also 50's models ford and chevy cars. Why am I bringing this up?

It was so neat to look under the hoods of those 28-30 fords and see the 6v genny with roundcan cutout on top of them... no regulator. Had the odd shaped distribuitor cap with metal arms going to each spark plug.. great vintage stuff.

Both the 50' fords and chevy's had 12v gennys and regulators. Was interesting to not that both the ford genny's and the delco genny's looked identical. And some models even used a similar wrap around band style mount that out N's do.

I got my NAA and it was already farmer converted to a 12v alternator. I cleaned up the wiring and it charges good.. just looks ugly.. but now that it is 12v.. I like it, as I can use it with some 12v items.. sprayer, etc. After seeing that car show, I am way tempted to track one of those 12v genny's down and mount it up... Who cares If I don't get 30-45 amps... 20 would be fine. Now I just gotta go shop prices..... . ho hum..

Happy easter to all.

Want a 30 amp generator that is an easy mount on an N. Try a 12 volt Bosch from a 67 to 74 VW bug. Mounts with a band has an adjustable pully that easily adapts to the N belt and develops 30 amp at 2000 rpm. No guesswork on wireing as both generator and voltage regulator are clearly marked. D+ to D+ and Df to Df. Also use the Bosch voltage regulator. Sorry the people who know bugs and Ns will be able to tell the difference.

If you do decide to go with a newer style conversion, and you have the side mount distributor,: genessee products has a nice conversion, and they also have an electronic ignition that drops right into the side mount dist, under the cap. Mine works wonderful!! I have an old ford 801 powermaster, and an 8N. Good luck.

Well, my 8n still has the oem 6v genny which is working good.. but my NAA came with an ugly alternator. I may have to look into these 12v gennys.

E-ignition might be nice too...
