    Hi everyone. I have a fisher 8' straight blade. The last time I was out it just stopped working. No up down left or right. Messed with the plugs and the lights would switch from truck to plow but still no movement. Replaced motor and fish stick and still got nothing. Only way I can get the thing to work is by jumping power to the hand held control. Any suggestions would be great. Thanks

    Do you have power to the controler. If so check for power at the selenoid when operating the controler also check your fuses check all your battery connections check your grounds too

    Try the ground at the plow. Add jumper cables from your truck batt to the plow gnd and see if that works

    the harness that plugs into port 1 on the isolation module has two plastic plugs with covers on them.Those are two fuses the 15 amp fuse is for park/turn,and the 7.5 amp is for the controller.Check to make sure that fuse isn't blown.Also check to make sure the black wire with the orange stripe is plugged into port 2 on the isolation module.

    The module has a b c ports all r plugged in tight and the fuses under the cover that looks like a port plug are good. Also with the fuses behind the headlights are good too. All connections are good. Took them all apart and cleaned them and put terminal protection on them to help slow down corrosion. I took a wire and jumped PIN number 2 and 7 and it still didn't light up controller. Do u guys think that the wire harness or module could be bad?

    Follow the controll harness from inside the cab at the plug back 12-18" and find the red wire coming out of the harness,this will leed to switched 12v,make sure it's still connected.

    That's what I love about this forum, 7 solid replies in less than 24 hours without any ball busting. Even still, most of you guys are probably out busy plowing yourselves. Good job men!

    The black & Orange ground wire with the black plug that jumps the ground from port one to port 2. is that supposed to have ground supplied from port one to port 2 or is it gound supplied from port 2 to 1? I seam to have lost ground to my 4 port module.

    Should only get ground when it's plugged into the plow.

    That much I already knew, Dieselss. Anyway, I determined that the ground connecter between the 1st & 2nd plugs was the culprit! so I eliminated the black connector and spliced the ground wires together. Now she's working just fine with the exeption of my 11 pin light plug that needs to be replaced (lights constantly flickering on & off)!
