Bought a new pump motor today. Wired it up and ran it long enough to check for leaks. I then pumped water to waste for about 10 minutes to lower the level of water in the pool. I then turned the pump back off to move the valve back to filter. When I went to turn the pump back on - NOTHING...not even a humming sound. I wired it the same way my old pump was wired - a black wire to the L1 and L2 and the green to ground. Any thoughts at to what could have happened?
