Pluming & wiring Hydraulics for brake press

White wire goes to a yellow on one of the spool solenoids and the other yellow on that solenoid ties to a yellow on the other spool solenoid. White wire comes out of controller.

It is a self contained unit, the reservoir is the tank on the end of the motor, this is a power unit for a dump bed for a pickup truck.

The cylinder is one of 2 being used

What are the 2 black things on the pump block?

ok the two wires that are wired together go to ground and the white lands with the green on the small motor solenoid terminal.

The white is butted into a yellow going into one of the solenoids so I don't see how it could/should go to the starter solenoid :thinking:
 
I meant the free yellow solenoid wire it looked white in the picture. I believe it to be the last free wire. as for as the hydraulic ports i believe port 1 and 2 to be regulated outputs and 3 would be the return.
 
They are pressure bypasses the way it I see it wired is the black is put on the large nut the one with nothing on it and you have to put a positive 12v cable to it,the double wire goes from the hydraulics to the small nut on the solenoid of the starter, the other white and green go to the hydraulics solenoids other wires respectively one will open one hydraulic solenoid the other will open the other hydraulic solenoid a negative 12v ground wire from a battery goes to the starter somewhere to ground it, pushing a button will take juice from the battery 12v + through the hydraulic solenoid to the starter solenoid opening the hydraulic valve and kicking on the starter, let off it stops push the other button and the other hydraulic solenoid opens and the starter kicks in ... So doubled up hydraulic solenoid wire to small nut on starter solenoid ... Black to hot side of starter solenoid ... Green and white connected separately to each of remaining two hydraulic wires .... Good luck

Relooking at the pics does both wires complete a circuit when you push the down button could you do a circuit test on the switch push the down and see if the black connects to the white and the green and if you push the up button does it only connect the black and green not the white and black , that will affect the wiring

I dropped it off at Northern Tool for a mechanic there to look at, haven't heard from him yet so it's out of my possession at the moment. Thanks for your reply. I'll get it back sometime next week and try that if he doesn't have it figured out .

Yes when you press down it connects the black 12v+ to both the white and green wire and when you press up it connects only to the green wire. they would never connect the solenoids through each other or electrically in series.
