On a pump should the neutral (white) be shorted to the power wires (black and red).?

I kept blowing a 20A fuse and when i disconnect the pump from the circuit board of my jacuzzi it doesnt blow. So, i got out my trusty multi-meter and found that white was shorted to the black and red (when disconnected from the circuit board). I dont work with neutral just normal groun so im kinda scratching my head. Any help will be greatly appreciated.
