[SEL] Looking for small alternator.

[kimmell at verizon.net]

Elden,
Why only 20 amps?  Most automotive alternators that I've messed with have a capacity of at least 60-80 amps, all the way up to 160 amps for the heavy duty ones.  If you're building a regulator it shouldn't really matter though.

Most of the older Ford/Lincoln/Mercury vehicles from the 70's and early 80's used external regulators.

Gang:

I'm planning on making a butt-buggy to be powered by the Homemade Hvid engine.  I would like to use a novel (but not revolutionary) method of driving the tranny, though.

I plan to generate 12 Volts to keep a small battery charged and to run a 12 Volt motor connected to a Sears Suburban (Interstate) transaxle.

What I'm looking for is a small alternator that will make a maximum of 20 amps at 14 volts.  I'd prefer a unit that requires an external regulator (which I will design and build).  I will make a flat belt pulley to drive it from a flywheel of the engine at around 4,000 RPM.  Used is fine as long as it works.  Cheap is excellent, as this project is running way over budget.  :-)  What else is new??!!

Whatcha got?  What can you suggest (make and model of something I can get the alternator off of at a junkyard.

Thanks and take care - Elden DuRand
