As shown in figures "A" and "B" of the illustration, the potable water pump trips out on overload shortly after each start attempt. In an attempt to troubleshoot the problem, the following voltage readings are taken during the brief run period: At load side of disconnect: L1 to L2 is 230 VAC L2 to L3 is 230 VAC L3 to L1 is 230 VAC At load side of contactor: T1 to T2 is 105 VAC T2 to T3 is 106 VAC T3 to T1 is 229 VAC At load side of overloads: T1 to T2 is 100 VAC T2 to T3 is 101 VAC T3 to T1 is 223 VAC What is most likely the problem? See illustration EL-0043.
