Nope; it is confusing at first glance, but the EV-1 *car* was a Chevy, while the EV-1 *controller* is a GE product ;^> > If we're talking about the forklift controller I can help!

The drawings appear to identify it as a "STD. K70C M500 SCR", but Google isn't any help figuring out if this is an earlier GE model or not. The person seeking help has a bit different situation than you or I (I also have an EV with a GE EV-1 controller in it), since he is electrically reversing the motor and so cannot simply eliminate the directional switch(es) and contactors like we did.
