I have a shallow well pump for my house and when it comes on it has begun diming the lights in the house. I can only assume that it is the capacitor going bad or the motor itself going bad. I have a healthy fear/respect for all things electrical and make my decisions for DIY on electrical things accordingly.

My question is, do you think it is the capacitor? Would you recommend I replace that capacitor and if so is there a better capacitor (soft start) that the others? If you do not think it is the capacitor, what else might it be and what can I do to test?

FWIW the pump itself is about five-seven years old and I have a 20 gallon pressure tank attached. It works perfectly other than the hard starts. Thanks, MG
