Converting Alterenator back to Generator
Sometime during it's life someone converted the 34 over to a 12 volt system using a 2 wire GM alternator without a voltage regulator. Not sure how but it appears to still be using 6 volt lamps and original amp meter? I came across a recently converted 12 volt mid 40's generator with a new voltage regulator and would like to convert it back to the generator mainly for aesthetics. There's plenty of info on switching from a 6 volt generator to a 12 volt alternator system but having trouble finding specifics on converting 12 volt alternator to a 12 volt generator. Thought maybe some of you guys may have made a similar conversion and might be willing to share some information or let me know where I might go to find out the correct way to make it work. I already had the screw on pulley with the 4 bolt fan attachment. I wish it was as simple as unhooking the 2 wires from the alternator and fastening to the generator but I afraid that won't be the case. Thanks guys!

Re: Converting Alterenator back to Generator
Speedway an others have alternators made to look like a stock early Ford generator. No real advantage in going back to 12v gen. As it still won't be stock and if just for as esthetics go with the alternator that looks like the Gen. & maintain the bennifits of the more modern alternators. As for your amp meter it doesn't care if it's 12v or 6v as its registering Amps not Volts. I'm sure either you have a resistor reducing voltage on the power going to your lamps or have 12v replacement bulb.

Re: Converting Alterenator back to Generator
I haven't seen anyway to mount the fan to those alternators your talking about and that's a real advantage to me. The last time I checked those power masters are running around 400 - 500 bucks so I think I'll stick with what I've got if I can't find out how to hook up the 12 volt flathead generator, that's really the information I'm looking for.

Re: Converting Alterenator back to Generator
No idea how 6v bulbs work on 12v, maybe something else going on. But; if the both are 12v and the same polarity, it should be pretty simple; mount the regulator and generator, connect the battery wire that was on the alternator to the battery terminal on the regulator, connect the field & armature wires between the generator and regulator. Remove the second wire that was on the alternator. Polarize it, should be good to go.

Re: Converting Alterenator back to Generator
I like the old Fords with stock appearing parts. I had several GM 6 volt alternators
given to me by a friend that had them on his and his fathers car for about a week. They said they didn't work as good as the original 6 volt generator they way they used them on short around town drives. These had stock pulleys. I put it on my 39 and found the same problem. Talked to the old guy at my motor, generator shop and put 24 volt stators in them and they worked perfect, slightly charging at idle. I didn't like the looks of the GM alternator and made 7 stock Ford alternators into 6 volt POS ground alternators. These have an adjustable regulator that I can adjust the output with a screw in the back cover to 7.3 or what ever I want. I would never be happy with a generator again.

Re: Converting Alterenator back to Generator
no personal experience here, but was'nt there some issues about running a fan mounted on the delco alternators and the shaft or bearing could not handle the load resulting in fans going thru the hood? do you still have the stock fan on your 34? that is a slick deal that GM made

Re: Converting Alterenator back to Generator
GM: Ever think of making and altering those for sale? Team up with your guy at the motor/generator shop and get that ball rolling.

Re: Converting Alterenator back to Generator
Great info here. I like your conversion GM and thanks for posting the link to FunProjects.com for that voltage regulator swanwaco32.

Re: Converting Alterenator back to Generator
Yes, It appears to be mounted to one of the speedway alternator fan adapters. I'd heard about that too. Another reason I wanted to change it.

6 volt alternators could be sold just through Ford Barn. The "old guy" has turned the business over to the younger ones. I tried a little to get them interested. When I go back up to Pa. in July I will go and go over it with the one running the shop now and get a approximant price of what it will cost. Then I will put the info with their phone number and email address on here and see how much interest we can stir up. G.M.

the front with another bearing so the fan is no problem. G.M.
