[96ChevyNorthman]

Hi yall! I picked up and old Northman Plow on a 96 Chevy 1500 last year and it worked great all season. A couple of days ago I decided I would check and make sure it was working and clean everything up and get it ready for winter. I lifted it turned it right and left then when I went to set it down it wouldn't go down. I have never really worked on a plow setup before and really don't know where to start. Could someone please point me in the right direction.

Thanks

Did a wedding band fall on it?

Thanks for the replies!! Yeah I know they are not very popular. I just went out and messed with it some and I tapped on the solenoids with a hammer and it went down but now it wont stay up and it sounds like the pump has tp pump really hard to lift it

Time for a GOOD clean and flush. I would pull all valves and clean then. Who knows how old the crap is inside. Doesn't take much to jack a valve.

Yea not a popular.plow at all. Not even sure there still.in business
If it won't stay up....generally cause by junk in the valve OR a leaking ram. Since you never mentioned leak, I would agree with pat and start with a fluid flush and a valve cleaning

Which pump system, and which control system do you have?

10813A. Control s are toggle switches up - neutral - down
Go up fine does not like to go down.

The instructions Hydro posted are right for that newer model. But here is the complete manual--will leave at end-
But, a few things- make sure the coil to the drop valve gets voltage when switch is in lower or float, and make sure it is same as truck voltage.However, those drop valves were known to stick, you may have to remove and clean it. Some can even be disassembled for cleaning. It is rare for a coil to get "weak" but can happen. Remember, it needs a good ground when installed.
