    Anyone know of a very small alternator that could be used on a HotRod and tucked in tight where it's not too visable? I'd prefer one with a built in regulator and maybe a one wire deal. My buddy has one on his Willys that he got from a circle track guy but nobody knows what it was made for. Some small off shore car I think. A typical Chevy alternator is too big for my application. Thanx!
  2. Try looking at fork lift alternators.Clark for example

    Grab the Nippondenso engineering ID#'s (100211-606, 100211-635 for this one) and head for your favorite auto parts store. They should be able to c/ref that number(s) and supply you with a relatively inexpensive rebuilt.

    Or 1987 Suzuki Samuri. In stock at Autozone. Kinda pricy at 99 bucks (lifetime warranty), but they are teeny weenie, 60 amps and come with a V-belt pulley.

    Great Info. I've been looking for one to replace the generator on my Farmall Cub tractor. Need a small one to fit up under the hood.

    If it is a SBC the water pump with built in alternator will work.

    I know some small Perkins Diesel engines have a very small permenant magnet alternator, as I recall they are about 4" on diameter and a few inches thick.

    I have a little one that I have been saving but not going to end up using. I think it will work out perfect for what you want to do. PM me if your interested. I can take some pics of it.

    Look for a Japanese Chevrolet Sprint or Metro (3cyl 1.0 L) in the bone yard. They came with a very small alt used by a lot of racers. If you have to get one from one of the common parts stores they are over $100.

    I'm not sure of the amp rating, but the alternators for a 87-93ish chevy sprint (3 cylinder version) are rreally tiny. The ones I've pulled off have a serpentine pulley on them though. The suzukis samuri or chevy tracker might be the same, but not really sure exactly.

    Haha, I was too late.
    Chevy sprint=Geo metro=pontiac firefly=suzuki swift (all the same car) but the 4 cyl engines used a different alt.

    Suzuki Samari, auto parts stores carry them on the shelf. Run a battery wire then a 12v ign wire and its done. As said before it comes with a single v-belt pulley.

    designs that work

    On Epay the small alternators are called Mini Nippon denso type, 45 amp single wire but a little pricey, over one hundred dollars. Have run one my avatar for 5 plus years.

    Like Fender says, we run the Kubota fork truck units both on the street and in our road race cars.

    A lot of the homebuilt aircraft guys,
    particularly, those building lightweight
    planes with VW or Corvair power, use
    an alternator from a John Deere garden
    tractor :)eek:!) that is really, really small.
    There's some pics and info on it here.

  17. sorry for this newbie question but do you mean that there are some water pump with alternator inside ?

    Man, there is some interesting info here. I'd guess there aren't any small units like the ND version that have more amps (50-60?) then? Gary

    I bought an 80 amp for a Suzuki Grand Vitara and swapped pulleys. Late '80's Toyota 4runner is 95 amps and v belt pulley. There are rebuilt units on Ebay with 130 amps, but I wonder about that much output in a small package. A search of Denso alternator on Ebay will show a bunch of outputs.

    I realize it's a bit of a WAG, what kinda amperage are we talking for a "conventional" rod with typical lights, AC and perhaps a Kenwood system, but not an outlandish power-hungry audio?
    Would 60amps do it?
  29. Cool info, am looking for one for my RPU,cheers. JW :)
