I try to turn on the motor, but instantly the power supply shuts down. What kind of power supplies do you guys use to power your truer?
I have a 30 amp PS that does the same thing. It's the surge protection that shuts it down. When I spin the tire a bt and then switch on the truer, it usually works.
What you can try is, to put a few big electrolyte capacitors parallell to your power output. They'll buffer the power surge.
