Yes, that was yours truly! Yes, the traction motor can draw that much, if
some safeguards are circumvented, and yes sustained loading at that level
will evaporate the fuse link! I spoke to Mr. Gunn when I made my last parts
order about "ratings versus real world experience".If the power pack is
capable of sustaining the load, and armature rotation is still
occurring,rated current draw, and therefore, horsepower and torque ratings
can be exceeded. Don't try this at home! Unless of course, you don' t mind
fixing it later!EV you later!

That wasn't what I meant.  I left out the units, my error, but I wasn't
talking
the mechanical load but the current.  Someone posted (as I recall)
600 AMPS!  I don't think the wires will handle that (that's the limit of
most
clip-on meters as well) so I doubt it.  I suspect 300 amps as a maximum.

>From Lee:

If that was me - - I said that I had pulled 500 or 600 pounds (a barrel of
water or 1/3 rick of green oak firewood) up a pretty steep hill (12
degrees). This is in 2nd gear (with my E-15). I seldom let the needle get
into the yellow, let alone the red, so I've never had any trouble with
over-heating.  I have no idea what the amps are.

I appreciate the note about the tractor pull.  I've often wondered what the
Electrac would do in one of those.
