Old UPS transformer. 4 wire input. Only one pairing seems to work. All other combinations blow the fuses. https://t.co/H3QpX7tjjq

Odd, expected it to be a multi-tap primary for voltage control.
Oh yeah, and three to run the E-brakes. Maybe another for the air valve. Can’t recall if that’s wired.
I think I’m gonna need a bigger arduino..
6 motors, each needs 1 PWM and two digital pins to control. Encoders will need 6 analogue pins for absolute, 12 digital for optical.
