Not following what you are saying with the ground of the pump feeding back into ground of bat 1. There is a normally open relay contact in the path unless the relay closes for clutch to be energized. Once relay energizes the batteries are in series. Works as drawn on the bench. Only difference between test bench and on car is I'm using a solid wire for ground instead of a frame.

I am using the reg clutch and the current draw when clutch is energized is about 2.75amp.
