From what I have gathered the "Both Up" Switch has gone kaput and the jumper for the hot has broken off, He said he could run them up and down with the individual switches until the power jumper broke which would tell us the pumps are good the solenoids are good as well as any wiring. It is a switch /jumper problem.

They'll go down, but not up. So I wonder if the failed switch could have taken a solenoid out with it?

I'm pretty savvy with simple circuits. So once I get some more time I'll try some things and report back.

It'd had to ruin both solenoids

I figured out the wiring, I think.

Orange - 12v
White - starboard tab valve
Green - port tab valve
Yellow - motor reverse, up
Red - motor forward, down

This is how my boat is worse from the factory, it doesn't follow the OEM schematic. The pump is a Bennett V351.

Found it to be broken connection in the boat's wiring. Kind of bitter sweet, it'll be a free fix just a ***** to find.
