Re: (ET) GE Motor Codes

["SteveS" <ssawtelle fcc net>]

My understanding is that the E12S is just like an E15 (including the same
motor) except it does not have the field weakening throttle settings (only 
3
forward positions).

The E12 (no 'S') has different wiring and I think it has a different
(smaller) motor.

There is confusion (at least with me) as my E12S is labelled as an E12 on
the hood. I found out it was different when I tried to repair it and
couldn't make sense of the wiring using an E12 schematic. Someone suggested
I try the E12S schematic and suddenly it was clear.

So in then end, you may need to check out the motor plate. I think one easy
way to tell the difference if the control panel is removed (large plate
under the dash, driver area), is the E12S and E15 use a small copper shunt
to measure current and the E12 uses a length of wire (20 some inches as I
recall).

It would be nice to have a timeline of the various models and what they 
had.
I've never seen much on it.
