Technical Making your Powergen more like a generator.

    Sometimes you just need to put a few modern things on the old hotrod. I like to keep everything as traditional as I can but when a generator can’t keep up with brighter headlight bulbs, small fuel pump, electronic ignition and a couple of gauges it gets tiring hooking up the trickle charger every night you take your ride out.

    Not sure if anyone has done or tried this yet but here’s my take on the Flathead Powergen. I already had an early 60s 12v Ford generator from Napa on the car. I think it’s about 25amps running full out. Bolted my front bracket mount to it and bored the fan generator pulley to fit. Now we’re at this point and spent the coin for the Powergen. Looking at it, it was ok in my eyes but needed some details to make it look not so powergen’y. Started by drilling two holes for dummy studs as a Field and Ground. The rear cover got the brand name shaved off also. I had the offy pulley but when I set it up it just looked stupid with the fan behind it. For giggles I popped my original fan mount pulley off the generator to see if it fit. Luckily the shafts are the same size and I put a few spacers behind it and tightened the nut.

    I kept my external regulator on my firewall but just gutted it and put a thick wire inside bridging ARM and BAT terminals.

    Now I know the late 30s pulley is a bit larger than the original that came on the Powergen but I think it will be plenty to keep the battery charged up cruising at night.

    To the untrained eye and folks walking by at a show or where ever, you’d think it’s just another generator. 94DE772C-E16C-489A-B2AF-43B3D2519D68.png

    @N49racer good idea. I could do that if I ever take it off again. Haha

    To most untrained eyes at a show it won't matter. But to people like us here, that's the kind of details that really count (I find there aren't people like here at shows in my area). I find myself sweating the details on my build because I am trying to stay within 1935 and older for the most part----or at least make it look that way. It's hard, but it'll be worth it.

    Good job on it, it looks great!.

    Until N49racer mentioned the lube fitting, I was fooled, ...not that it takes much. Good job, it looks right at home.
     
  10. Good job! Might have to borrow that.

    Heard that PG is coming out with a alt/gen with a stock looking cutout on top.

    @hotrodA well the powergen for the 4 banger has a cutout on top of it already. But yes you could just get a cutout and bolt it on.
     
  12. Nice job ! Thanks for sharing !

  13. I used a 28 Model A Powerhouse Gen and put a Kabota PMG inside. Puts out 25 amps and that is enough for my needs.Gives me room for two carbs on my early Roof intake.

    @27TV8 very nice. I needed more than 25 amps. When driving at night I was watching the volt gauge drop slowly. Day time driving with lights off it was fine though. My headlights I have wired with low and high beam on at the same time so I can see but aren’t blinding people since the headlights are low to the ground.

    I love your idea.
    I guess I am lucky but my flathead pickup is running an actual 60’s Ford 12 volt generator and I have an MSD with a fuel pump and an electric fan and sealed beam lights.
    It’s able to keep up with no issues.

    Cool tech and thanks for sharing @JT1930 does it run hot? I would love to see @27TV8 tech or more info on the powergen conversion with the tractor alt.

    @Petejoe different patty’s could be pulling different amps. That’s good you could get away with the 60s generator. I wish that was the case for me. Now you got me thinking maybe my external regulator wasn’t staying connected long enough. Too late for that now. Haha

    @continentaljohn been running cool but it is also cool in my area. Around 60-70*

    I was going to say a generator in good nic has no problem with halogens and electronic ignition. But I understand trying getting away from them.

    Not to discount what you did here, but if someone is going to spend the coin on a powergen but wants a more authentic look, then just buy a Whitney. They are much more authentic looking, they even use the original front and rear plates. https://www.ejwhitneyco.com/automotive.html

    Since I’ve never had the opportunity to try, how do they handle in comparison to the un modified versions ? :D:D

    @Blue One if the coin was spent they handle and feel quite well !!! Hahaha

    @Automotive Stud this is the first I’ve heard about that company mentioned but still only 40amps max they are producing. I’d rather have the 90amp powergen just in case I put more electronics on. All my gauges are electric also with lights for night. But thanks for the site info.

    Nice clean attention to detail. I would not have known, and that's pretty much what you want. My old car has many non- traditional things on it. But, I try within reason to keep it at least so it looks like it came that way. I'm the only one I have to please, so it's workin' out perfectly.

  25. @Ryan , you do realize a few of us HAMBers sent Eric at Powergen originals so the could develop the Powergen? I think I contributed 2 or 3 GM Gennies myself

    Taking a different route with mine. Being a Packard guy and always looking to dress things, I'll use the same finish and I also have an old Autolite tag to install. Not looking hide the Powergen, just give a little extra zoot. Same thing on the starter too but not many will notice. Very kool work, and I understand the need. I'll be hiding an amp and sub so output is nice to have when the tunes are thumpin.

    I can spot a powergen from 5'... Easy...

    And that's not a knock really... I think they are great alternators... and would certainly rather see one than your typical gm one-wire.

    I just like the extra detail from JT1930 is all.

    The kind of thinking that JT1930 is using, is what makes this genre of the car hobby so good. A lot of the car hobby as a whole is just bolting on parts from the aftermarket. There is a deeper level of thought as well as skill that goes in to traditional hot rodding.
