GE EV-1 control panel
| < prev. photo | next photo > |
Here's the brains of the forklift.
This control panel includes all the circuitry, fuses and contactors (big relays) to turn the two hydraulic pump motors on & off, as well as the power steering pump motor, plus various contactors for safety and change the direction of the drive motor.
Several of those contactors are in use in the car.
At the top right of the panel is the GE EV-1 motor controller for the main traction motor we originally thought we would use in the car.
