That's what's confusing to me. Since there is no relay in the control box, it must be built into the motor?
Then either way, there is momentary voltage through the capacitor leg and then when it's up to speed, there should be none and switches back over to hot to run?
Yeah, different way to design a system. Less starting torque I would think.
