Hi....I have a Hayward Max-Flo II 2 speed pump that trips the breaker instantly when turned on....I have 250 volts between the common and high speed wires during high speed operation....but also have about 70 volts between the common and low speed wires....this is when it's in high speed.....when I switch the speeds....i still have approximately 70 volts applied to the pumps windings that aren't being used....is this normal....not sure if it is....reason for asking is because I've burned up 2 pumps in less than a year....I didn't do the electrical...the labels on the outside of the motor are burnt....like if the motor is getting extremely hot....any ideas???
