tabs

Hello, I've checked everything, cleaned switch contacts, cut out and spliced pugs, removed the relay, checked both solenoid O rings and springs, and still with just one switch, either switch operated, both tabs go up or down together...? Is there a barrier inside the pump that could leak...

I am at my wits end. I installed the relay, atc, and control unit. The system was working correctly before Install. When I put system back to original setup it still works correctly. I ran 8 wires from the relay box to the helm. When I put a loop on the 8 wire at the helm I can use it...
