Bought this bike used. Radio worked, then it quit, then it started working again & now I think it's down for the count. No radio lights, no cassette player, no clock, no noise through the speakers - nothin'! Both fuses are good. Checked the 23-pin connector at the radio with a test light and found three pins powered - two through Radio Memory circuit and one through Radio Power circuit. Anybody know if more than three pins are supposed to be powered? Anybody know if there's a fuse INSIDE the radio????? Wow, there's a wad of wires under the hood! Makes my old bike look like the electrical system on my Schwinn by comparison.
