I have a 15 year old Blue Heaven pool. It had a 2 speed 2.5hp pump now it's a 2.0hp. The pump and Jandy P-Link dual timer went bad at the same time. Insurance paid a guy to replace the pump but they would not touch the timer. After the pump and timer was replaced. I got up the next morning to check every thing out. the high speed kicks on for 2 hours then the low speed comes on. As soon as the low speed comes on the motor growls. They thought it was the new motor and so they changed it. The problem is still there so I am switching the timer manually. From what we have worked out both sides of the motor high/low are coming on at the same time. The wiring has been checked by the guy that replaced the pump motors and found nothing a miss. Well it has come down to me and my pool guy working this out. What I want to know is on the back we pulled the inspection plate on the motor. The lugs read 1 2 3or4. What is it #1 common #2 High #3or4 Low? Any help with this will be greatly appreciated.
