    Hello, everyone, yesterday i left a t-shirt on the catwalk, and i forgot it, well, it was blown and stuck in the driveshaft and it was hitting the wires on the frame to the point of peals like 10 of them and stick them together, looks like that make a short and now i have the ABS light on, and the speedometer is not working. Is not reading speed. I tried to find a blow fuse but everything is ok, i replace the abs module and Speed sensor and the problem is still there. Any idea if there's another fuse? For the abs or sepeed? I checked all fuses under the hood and on the center dashboard. I'm driving crazy with this.
    Need help with this please.
    It is a 2014 VNL 780 with 10 speed eaton fuler manual transmission.
    Thank you so much!!

    The t-shirt didn't blow a fuse, it broke a wire or a few wires. You need to CAREFULLY inspect every wire that could have been damaged by the spinning shirt or at least every wires in the area that are used by the ABS and the truck speed sensor. Not every broken wire will be torn in two pieces. Sometimes a wire will look intact but have a break in the conductor under the insulation. With no power on the truck I would do an electrical continuity check on every wire near that part of the frame. You just need a $30 ohmmeter with probes and some time to poke each tiny wire.
