No power at aft bilge pump

I noticed my forward bilge pump running when it should not. I check the float and it stayed on. So I cut one of the power wires to it for the time being. I checked the aft bilge pump and it was not going. Turn on the manual over-ride switch at the helm and still nothing. I cut the wires to it and checked them for power with the switch on at the helm. Nothing. I checked the bilge pump breakers at the battery panel and they are pushed in. I pushed them again for good measure.
The wires for the aft bilge come from a bundle so not simple to trace. I would suspect the float switch, but doesn't it just work in parallel with the switch at the helm?
Not sure what to look at next.

Also, and maybe I'm reading it wrong, but I'm having a tough time tracing the relationship between the helm bilge switch and the mid bilge pump. Other than something called Bilge Relay Batt Selector, which again, no idea it's located.
Has anybody else had to debug a similar issue? I'm sure it's something dumb.

I did find the problem, not the cause though. The ground leg of the circuit was not good. I was able to read 12v between the hot wire for the pump and the engine block. So I ran a new ground wire from the pump to the ground block in the bilge and she works. Not sure if I'll every find the cause of that bad ground.
Anyway both pumps work as expected now. On to other post winter gremlins.
