    Based in the size of the unit, the unit's lack of cooling provisions, and the size of the wire coming out of the unit; sustained output ability is low.

    Looks like some I have seen on Deere's. Suprisingly the output is higher than you would think. Output is determined by how fast you turn them.

    That looks to be a lawn tractor alternator according to this ebay add 360452148174
    It could work ok on something like a little modified roadster that didn't have any accessories on it.

    They used to sell them as racing alternators nothing more than a magneto seems like they worked pretty well as far as I can remember

    Most permanent magnet Kubota alternators are 20 amps or less.

    ....... well, sort of. And, output is limited by how well the unit can cool itself.

    I agree with sunbeam, it looks like a permanent magnet unit. That means a non-standard regulator. Be aware that some of those regulators don't regulate well enough for some electronic devices.

  10. These are neat little compact units,[14 amps output]-I bet they wont actually cut it for a car's useage....
    I had a motorcycle once that had an alternator producing 19 Amps.
    It worked fine on the factory bike,but when a set of aftermarket running lamps were added it woud not keep up.
    at night with all the lights on it would not charge the battery adequately.
    And that is a much smaller/lower cold crank capacity battery than what a car runs.....

    I agree, even if the unit could tolerate being run continuously at full output, 14 amps isn't enough to run the engine and lights at night, and charge the battery.

    Did a little research. Deere has a 35 amp system just like this. Part # AM220339, problem is cost. That little gem is $340.00. Then there is the regulator for it part # MIA881692, again the cost, $268.00.

    That is a little expensive for my taste, but should work fine if you are not going to have a ton of electronics.

    They use similar alternators on experimental aircraft. Deere sells them at a very high markup, there are other suppliers (kubota I think) that sells the same item for about half the price.
