Schematic time...



(With thanks to http://www.evconvert.com/eve/schematic-update)

It's pretty simple, but I'm sure we've overlooked stuff. Fuses?

1. Amps and Volts are always on. (Is that bad? I thought it would be nice to be able to stick your head in the window and check the voltage without having to turn the key.)

2. Switching on the ignition activates a relay that sends power to both the pot microswitch, the controller Key Switch Input, and brings in the pack -ve contactor.

3. Pressing the go pedal a tiny amount activates the pot microswitch which pulls in the pack +ve contactor, activates the "hours" meter, and makes the controller "live".

4. Pressing the go pedal further moves the pot wiper which the controller interprets for controlling the motor.

EDIT: so I have 2 possible escapes from a full-on controller failure: releasing the go pedal, and/or switching off the key.

EDIT 2: the hour meter is just for fun. It came with the forklift, so why not use it
