Subject: (ET) lift motors, almost, but not quite....

So this evening I replaced my forward lift motor with a spare from a 71
Buick. They look the same, but of course you have to open the Buick
motor and run a wire out from it as they are shipped with a common
ground (ie: car).
Not the same amount of power, unfortunately and not the same windings. I
was wrong last night when I said the elec-trak lift was the same as the
Delco car lift. It's not. Proof in the pudding: Swapping a buick
armature into the elec-trak's body (field) made the armature run slow
and pull a lot of current. Field was imbalanced and since this is a
series motor that's a problem.
With the Delco motor you really can only run it at 12 volts. I'm going
14 myself because I have infinite taps with the NiCD batteries. It pops
it's breaker more often than the old one did, which is a serious
problem. If it's having this kind of trouble with the mower deck it's
not going to do well with the snowblower.
*sigh* So I guess our options are either find motors, somehow rebuild
them, rewind them, or go in another direction. Anyone ever replaced
their lift with a small 12 volt winch?
