Thanks for the replies...its not actually my pool...but a customers...in order to read the voltages....I had to disconnect the wires from the pump itself....cause otherwise it trips the breaker instantly....so I dont believe its the terminal block on the pump....that seems to be ok....the customer bought a pentair control system with a 2 speed relay and installed the system himself....he claims that the 70 volts applied to the not used windings shouldn't be a problem....I think differently....customer claims the pentair system is 100% wired correctly.....guess we'll have to check....my question was the 70 volts....sounds like the above post agree with me....by the way....this customer claims to be an electrical engineer.
