Anyone know how to get a Grant horn button to function and not just spew sparks? in Interior, Seats, Door Panels, Trunk, Glass, etc Posted October 19 On 10/13/2021 at 12:19 AM, Omie01 said: Also make sure that your steering wheel nut is not grounding out on any of the copper, this is what I ran into. The peaks of the hex just touched the copper enough to pop my fuses. Had to grind a little off the nut. This was also the case with my Grant Challenger set-up. At random times while turning the wheel I would hear one of the flasher cans operating in the dash, though the blinkers were never flashing when this happened. Turns out the peaks of the hex on the nut were just touching the horn copper, enough to catch a bit of current and somehow direct it to the blinker switch circuit. So I ground off the peaks a little bit and never had the problem again!
