    So I have had my 8' fisher straight blade for about 8 years, and it has been on my 09 f350 for the last two, was going to wire wheel and paint the head gear today as well as change the fluid but when I hooked up I got nothing, put the plow on my uncles 06 and everything works great, so back to the truck side. I changed the selonoid on the fire wall and I can't get power from the selonoid to the plow, I checked the fused link in the cab an it was fine and had power, all the fuses on the ISO are good, and I cleaned all the connections for corrosion, I tried three different controllers and none of them will light up, I have no movement and no lights and I can't see any pinched wires, is it possible to have two bad selonoids? One was brand new from fisher, or should I be looking at the ISO module?

    Is the smaller red wire on the battery side of solenoid?

    The only red wire I know of is by the connector harness I'm the cab that goes to fused power, there's two black stripes wires that go to the selonoid on smaller posts then the power, I also cleaned all the grounds
