Ive got a 92 K75/S ABS and ive had the bike diagnosed at engle motors in KCMO the ABS light flashes even after the breaks of been cycled as mentioned in the owners manual. both ABS units are working properly, what i was told is what is causing the problem is the alternator even though its charging the battery to spec. the problem is the altinator needs a diode on one of its wires. this is what was passed down to engle motors from bmw. now they werent able to tell me what spec of diode is used. so is there anyone here that can tell me.
