    Good evening. New to the forum. I have a 89 Ford F250 with a Diamond Plow on the front of it. It has a electric hydraulic Pump. The pump is a JS Barnes Pump. Now it has power to it, when I move the left, right, up and down the pump runs, but the plow doesn't move. The lady I bought off of says that the think they ran the pump without oil. It was low. I added the oil needed and it still doesn' t move the plow. Does anyone have any information or know of a site that could lead me through a troubleshooting routine? Thank you in advance for any help..

    So what you have there is a pump with a seperate valve body which was pretty common back in the 80's.

    You need to verify that the pump is putting out any pressure so your going to have to get a hydraulic pressure gauge (min of 3000 psi) . You can either T into the pressure line or go staright into the pressure gauge from the pressure line. Since theres 2 lines coming from the pump you may have to try both lines to find the one that builds pressure. Start with that and lets us know what you get for psi.
