===========================
Good points you brought up, Chris.
I have repaired several GE lift motors myself, and had several that were
not
repairable. I have now sold all my GE tractors, but still have a New Idea
that
I use. Most of you probably know that the New Idea lift motor is
completely
different from those on the GE's - it is not a window lift motor, but
appears
to be a heavier duty motor designed for this use. I have never had
occasion to
work on this motor, as it has never failed. I also heard on this newsgroup
that some of the NI lift motors were actually rated at 36 volts, rather
than 12
volt/used on 18 like mine is.
Since the NI tractors were actually built by GE, (as I understand) how
does
it happen that the lift motor is different? Did New Idea demand a better
motor,
or did the later GE's also have this better motor?
Would someone out there with more knowledge than me enlighten us on this ?
