Since the load hasn't changed from before and after, I'm going to start with flandrax' theory and investigate the start capacitor. I'll run a test to calculate it's capacitance and post back to let you all know. Otherwise the motor will have to goto a shop for the bearing and what not
My pool pump motor blew the starting capacitor last week and I replaced the capacitor today with one of the same rating. The motor starts and runs fine under no load but once it starts to prime the water and take on load, the starter circuit starts cutting in and out. Any help would be...
