Hayward Superpump 1 HP set up as 220V. Tried to turn on first time since closing in October but didn't turn on. Timer has screws A, 1, 2, 3, 4. When I test with multimeter I am getting the expected 120V on screws 1 and 3. But with the timer switched to Off, I am also getting 120 on screws 2 and 4. Is that normal? When I do switch the timer to On, I hear a click and buzz and the pump gives off some smoke. I am going to replace the motor, but wondering about measurement when timer is switched to Off. I would expect that to be 0.
