    Plow is a old hiniker on a 96 gmc 3500. Was Hardly moving and draining really bad on the battery, we found a bad ground in the power plug so we replaced the harness truck side. Now the plow works normal speed but only goes up even when moving it sideways and drops after you let off the switch. Any suggestions?

    How is your fluid level?

    Was fine when I checked it before I replaced the harness.

    If fluid level is still good, I am going to lead to a stuck solinoid or valve.

    Someone who works with Hiniker plows will chime in get you on the right track here. If it was a Western, I could get you going down the right path, but I don't know Hinikers. Sorry

    Two problems are occurring. First, no valves are activating when the motor is running. Second, the float/release valve is stuck partway open or has power when no function is active.

    So what's the solution?

    Your problem is very likely electrical. It is vey hard to troubleshoot over a forum thread. I would suggest getting the plow to a dealer. If that is not an option, start with getting the electrical schematic for your plow. Check for power at the coils at the appropriate times. If there is power at the wrong times, then Find points in the wiring harness where you can check for power without probing the wire.
    I'm not saying that your problem might not be simple. It could be as simple as the wrong kind of grease at the truck plug but it requires troubleshooting to figure out the problem.

    Edit: after rereading your opening post. It is possible you used a new style black truck harness to replace an old style grey loom truck harness. The two are not compatible and would require the plow side harness changed to the new style as well.

    I always use dielectric grease. Is that the right kind or wrong kind?
