we have two h2o pumps that are controlled by an alternating relay to share their run time. Problem is that if we are away and one of the motors goes out on overload the relay will latch onto that pump and not cycle to the other pump. Any ideas on how to draw a circuit that will sense the load, so that the relay knows that the pump it cycled to ok to go??? Ihave looked for a "smart relay" that can sense if there is a load but no luck .Thanks
