The signals were sketchy before and then all of a sudden they just quit but when they did, some dash warning lights started to flicker then stopped. Everything else works - emergency (4 way) flashers - horn - wipers, fuses are good, etc., etc., Two questions...(A) does anyone have a wiring schematic to help me sort through all the multicolored wires? Perhaps a Justy uses the same wiring codes??? Yes? No? (B) Of the 3 wires (green - yellow - black) going into the flasher only the yellow and green are active with the 4 way flashers; what purpose does the black one serve? A ground going back up to the switch? (C) All right I lied...there are 3 questions... There is only one flasher module. Can the 4 way flashers work and the signals not work indicating a defective flasher can?
