I have a 1 1/2 hp pump, that pumps water into a holding tank, controlled by a float. Living in Texas with the prolong power outage. With a new control box pump will run for a few seconds, then relay will chatter and overload will trip. I have 118 volts on both legs coming from contactor and breaker. My ohm readings for the pump are: Yellow/Black 2.6 ohms (spec is 1.7-2.1), Yellow/Red 8.8 ohms (7.1-9.2), Red/Black 11.4 ohms. Well is 16 yrs old, pump set at 175 feet. We do not have a pressure switch in the system. Any help would be greatly appreciated, about ready to pull my hair out.
