    Snowman LD75 plow was working ok, but quit,
    now will not raise. Angles left & right just fine.

    What's the best way to troubleshoot the cause ?
    Thanks

    I sent mail to Snowman Snowplows and got an immediate reply from Ed, who was very helpful in determining the cause of the problem, which was in the controller.

    After looking at the controller I found the raise micro switch had been replaced by a previous owner. Although connections looked ok, buzz testing showed the trace on the printed wiring board was open. By soldering a wire across the trace I was able to get it to work.
