I have been out in the shop playing around with it and have found that the 20A fuse on the bottom shorts and burns out. The markings on the box are not readable. Also the one I can read says instrument and it has no power to it. Could the instument fuse make the lights not work? Can someone tell me what the fuse is on the bottom of the box. I am hoping that I can fix it because this harness is not cheap! Thanks EB
