Someone may have solved the problem but I haven't heard about it. I hate the look of an alternator on an old flathead unless it has been reworked to fit in a generator housing. I would look for a 2 brush generator with a front mounted fan and have it converted to 12 volts, an easy job for someone that knows what they are doing. These generators will be hard to find, keep looking, calling, and posting ads. It has been several years but I think they were for '39 standard among others. I would go 12 volts negative ground (not positive) since that is what modern cars use and you can therefore use modern accessories. Other topic, paint the inside of your tail lights white or line them with tinfoil.

I have an electric fan, but could not use it at a prolonged idle (where it was most needed) as the generator would not keep up with it at idle. How much of this was caused by 80 year old generators that had not been properly re-built, or my ineptitude in trying to adjust the voltage regulator, I do not know. I saw several alternators from well known sources that looked like the correct generator, but had what appeared to be GM fan/pulleys on them-I could not stand the look. I think it was from this forum that I found E. J. Whitney, who takes stock generator parts and makes stock looking alternators with stock-looking (although slightly smaller diameter) pulleys. I brought him an old generator as a core. I think it took 4-6 weeks for the finished product. It wasn't cheap, but it was well worth it,IMHO, and I was able to keep my 6 Volt positive ground setup (and my stock radio). I have had one installed for about two years now-it has been working great so far.

RAK402 does E J Whitney still make these? What is his contact info? Thanks carcrazy 06-03-2023 @ 12:27 PM reply profile send p.m. Senior Posts: 1651 Joined: Oct 2009 Thirtysixford, I have what is believed to be a 1937 Ford 3-brush generator which originally had a generator mounted fan. This unit is available. If you would be interested in purchasing it as a core to be made into an alternator, please send me a PM.

This is where people are looking now. I used the "Brakelighter" third light in my all original 1936 and it worked great. It works with turn signals as well. It can be mounted with suction cups if you want to hide it when showing your car. Very easy to install. This is a brakelight, not a taillight, so keep that in mind. Also, how about adding reflectors, there are some cool vintage ones so they won't look out of place, or clip on/magnetic lights to supplement your taillights in the rear if you choose to drive at night, these can be battery powered or rechargeable, so don't draw on your car battery. thirtysixford 06-04-2023 @ 1:04 PM reply profile send p.m. Member Posts: 210 Joined: Oct 2009 Stumbled upon this https://www.jalopyjournal.com/forum/threads/early-flathead-ford-v-8-generator-2-brush-vs-3-brush.1205314/ CharlieStephans looks like you nailed it. thirtysixford 06-04-2023 @ 1:28 PM reply profile send p.m. Member Posts: 210 Joined: Oct 2009 How did I miss this? https://ejwhitneyco.com/automotive.html they are 20 miles from my house RAK402 06-04-2023 @ 2:18 PM reply profile send p.m. Member Posts: 436 Joined: Jul 2015 thirtysixford, I just came back in, sat down at the computer, and saw your message. Looks like you have already found E.J. Whitney sir-sorry I was so slow. thirtysixford 06-04-2023 @ 4:01 PM reply profile send p.m. Member Posts: 210 Joined: Oct 2009 RAK402 no problem at all I wouldn't have found them at all without your help Calling them tomorrow morning carcrazy 06-04-2023 @ 8:58 PM reply profile send p.m. Senior Posts: 1651 Joined: Oct 2009 The last year for the 3-brush generator (with generator mounted cut-out) which had the generator mounted fan was the 1939 Ford Standard. 1939 Ford Deluxe model and all subsequent model Ford passenger cars had the 2-brush generator (with external voltage regulator) and remote mounted fan.
