Question about 1985 Chevrolet Chevy

2 Answers

I just bought a 1986 chevy 1/2 ton with a fisher plow. I hooked up the plow and it won't go up or down, or left or right. The controls work, if I move the pistons on the valve body it still does'nt work. There is no load on the pump. it turns free, and is full of fluid. The truck has sat in a garge for the last three years and has not plowed. I think the up/down piston is stuck too.

Un bolt the motor from the base, the pickup is just tin, they rot off and fall into the base. you may have valves stuck too, but if nothings moving and pumps running, it should labor BADLY

My fisher minuteman 2 plow will go up and left and right but will not go down


Most of those systems don't have a driven retraction on the piston. It is gravity feed back. There is a valve that is sticking or out of adjustment. http://library.fisherplows.com/?cat=38

I have a fisher minuteman plow it will go up, left and right but will not go down what is wrong with my plow


If you have a Minit Mount two it's probably the valve sticking. It's electronically controlled so if it clicks, then the solenoid is working and the shuttle in the valve is stuck. Can be disassembled and cleaned. New ones are best but pricey.

I have a fisher minute mount an older model with fixed controls. plow goes up and down but does not go left or right, sometimes with the control set for left or right it starts to go up ? where to sta


check the wiring connections on the plow solenoids to be sure they are correct, the second step is check the controller box, using a continuity check via multimeter set for DC voltage. I have an old western plow that had similar symptoms, and was the controller box.

My fisher plow control unit will not turn on


I have the same problem, I do see the power light come on when I hit the key to start the truck but it goes out when I let off the key. If I park it in the garage with the furnace on it stars working and is fine until I don't won it for a day or two then its dead again. No idea why control is dead or sitting in garage with the heat on gest it working.

Not sure how to hook up plow motor to battery? Its an old fisher speedcast plow with cable controls thats electic over hydralic.It has pos and neg. cables and a solenoid on the pos. cable. I assume you...


The heavy + should be connected to the battery through the solenoid for the motor. There should be wires to control the solenoid (an electric switch, you know). The - goes to the truck's frame at a place of your choice. The ground must be solid, you know that, right?

I think if I were doing this install, I would hook the plow ground with the battery ground on the fame or where ever it is located.

The plow control should be mounted for your convenience inside the cab.

Lets review: Plow motor | ground to ground, hot to solenoid (motor side) | solenoid (battery side) to battery | solenoid control wires to cab.
