    I have been having issues with my plow the last few storms it wont raise all the time. The motor runs but will not raise the plow all other fuctions work. I put a new diode & motor on. Now after that I tried it and now the plow controler lights flash when trying to raise and it dont raise, But the light will stay on if it does raise. Also if the controler wont raise the plow and I go use the power switch to raise it and I blow the inline fuse in the cab. But if the contoler raises it, the power switch works fine also. I Clean the plow and trucks main wiring harness and put it back together. I am thinking its the connection between the two. Do the truck or plow side harness go bad?? The plow is about 10 years old. Please help snow tomorrow.

    Ok. What happened if you put the old diode pack.back on?
    Did it originally have any issues with it going left of right?

    nope only when raising. even with the new or old diode. If it dont raise all the other fuctions work. The motor will run but not raise. It seems if I wiggle the main harness connection it will raise.

    ive been having issuers on my older 810 (2003) with the plug being worn on the truck side plug. i had to take a very fine screw driver and bend the connectors together.

    Well try wiggling the harnesses. Only other thought I has was the pump

    Check for continuity/voltage at the white wire on the ten pin connector while your buddy is hitting the raise switch on the controller.

    What should the voltage be at the white wire? I will look at the truck side harness better tomarrow. I do notice when I wiggle the harness it works.

    Also what would it be if the volts are to low?

    You're just looking for current. 12v or nothing.

    You probably have a broken or chaffed wired in your truck side harness

    I had Stonebrooke put s new truck side harness in my 05 a couple years back. It was cheap insurance and fixed these little problems.

    Have you cleaned and repacked with dielectric grease? I have had that issue before, not enough dielectric grease.

    I have cleaned and repacked the harness. We plowed around 10 hours with the storm. The guy who runs it said it acted up a few times each time he wiggled the main wiring harness and it worked, so that must be it. I will look closer at it today.

    Broken pins? I have a truck with a broken down pin, actually 2 trucks. Wiggling fixes it.

    Find a machine screw that is about the same size as the pin, grind the head off and round it off. Where the broken pin is drill a small piolit hole. Thread in the screw that you cut the head off in till you match the same height as the others. I
