I just bought a 1986 635csi. Because it had not been driven daily, the battery went dead and I replaced it. It started fine that day but when I went to crank it up the next morning, all I heard was clicking. The wierd part is: 1) the battery is fully charged, 2)battery cable is good. The clicking seems to be coming from a "black box" forward of the brake master cylinder. I've tried everything!!! Is this a case of the starter failing by coincidence? Anything I may have missed? Thanks. Rob '73 3.0CS '86 635csi
