1. I have a spring run-off.
  2. I have 1 effluent pump 240v with piggy-back float switch as primary pump
  3. I have 1 effluent pump 115v with piggy-back float switch as secondary pump set to higher level to come on when pump #1 runs full time.
  4. Originally I had 2 115v pumps and put a 3-way into piggy back to plug in the pump and an indicator light so I knew when they were on both intermittently and full time. 5 When I acquired the 240v pump, the piggy-back has power all the time but the pump only activates when the switch indicates, so I cannot use the same system for a warning light.

What do I need to do to have the 240v system activate an indicator light only when the pump is activated?
