Hi, Rusty....many of the road calls I have to go on for tractor-trailer units involve blown fuses, and often it is just that the fuse is no longer making good contact in the fuse holder (fuse block).  On items like windshield wiper motors, often all I have to do is just pull the fuse out a little bit and push it back it. Windshield wipers start working. This often happens on fairly new linehaul tractors, 2002 models and newer. (Volvo).  Paul Conner

    You've been working field service long enough to know
    that fuses go bad, too.  They de-solder; they break due to
    vibration; the ends corrode and lose connectivity.

    I've seen this happen on cheesy fuse holders.  I have never seen,
    or heard of it happening on an automotive fuse.  Now, don't start
    telling me stories of some crappy old car that had rats in the
    fuse holder, because that ain't comparable.           I have items like fuel pumps separately fused, and to the wiring
    rating, so they should never blow unless there's a good reason.     Items like the EC-2 are directly tied to power, via two attachment
    points.  This is how Tracy recommends it, because the controller
    will be it's own fuse.           If I had the panel space, and believed CB's offered any
    significant benefit, I wouldn't care about the cost and weight.           Gotta go pick up my new company van, and replace a switch in Mobile.
