I am working on a 1992 400sel, the battery light is on while running, I have checked for charging at the battery and the alternator, both only show battery voltage. I have battery voltage on the main wire on the alternator, but nothing on the smaller wire that comes from the ignition switch with KOEO. I have had the alternator tested and it tests good, the battery also tests good. I have one fuse that is bad but it is for the seats, it is another problem for another day. I am trying to trace the problem down on the smaller wire to see if it is a bad ignition switch or possibly a broken wire or a bad connection somewhere. Can somebody pass on some information to help me trace it down or at least point me in the direction I need to be looking.
