Was wondering if anyone has experience with a solenoid operated control valve driven off a front mount pump. It's on a 1994 Ford L9000 that was a plow truck. Sometimes the hoist works great but other times you have to keep trying it to get the hoist to work. It has a Rexroth pump and solenoid valve. I've heard they need pilot pressure to operate but have no idea how to adjust this. It seems to get better if you use it more or I drive a longer distance before dumping. Always has 12 volts when checking with the solenoid activated. Any suggestions are appreciated.
