Yes,
E-mail to Don the photos as he has the drawings. Two relays is all you need to reverse the motor. One motor has three leads, the first is the common return to the battery, The second & third wires run the motor clockwise then counter clockwise. Then the next relay energizes the second function like up & down. You wouldn’t hurt the actual pumps as they are made to reverse. Next the hydraulic cylinders have two ways of building them. They can be single or double acting cylinders. The single acting cylinder has one port for pressure which pumps fluid to raise the motor. Going down it uses the weight of the motor & no fluid is pumped. It operates by the weight of the motor & opens a solenoid valve that opens & returns the compressed fluid back to the reservoir. The double acting cylinder opens two ports on the cylinder & one side of the piston gets filled by the pump & the other side of the piston gets evacuated back to the reservoir. this makes the cylinder change directions. Reverse that & the cylinder changes direction. There is more to it but that is the basic operation. Now if you connected the up & down wires to the battery thru the solenoid it would not be good on the relay or the pump motor. You may of caused a dead head too where the pump is running trying to move fluid & no ports were opened.
Hope this helps & THANK YOU DON for your help!! Don would you send me a drawing so I can learn too?
God bless you! Jeff.50@cox.net.
