So my 25 year old 1/2 hp gsw pump gas decided not to work.when powered up it will only hum then it trips the breaker. I tried to help it along bu turning the shaft with a screw driver but it still wont spin. There is quite a bit of resistance when i try to turn it over with a screwdriver. Im gonna try to get it pulled apart this weekend but was looking for some possible reasons as to why it malfunctioned before i do.Thanks
