Got a new pump for a customer today. Wired it up, plumbed it, and when I turned it on it makes a loud stressful noise like it is trying to get started but it never does and after 30 seconds or so it kicks the internal breaker. The motors voltage is 230 which is what we need. The impeller is spinning freely by hand. The wires in the back of the motor are all secured with the right contacts. The two wires going in to the capacitor are secure. What the heck is going on here? Please help if you can. Thanks.
