1983 300SD was brought to me to replace the ignition switch becasue it was getting hard to open. Customer had already had the tumbler replaced a year ago with a dealer part. I suggested to replace the ignition assembly w/ electrical portion and the tumbler. When he brought me the car last week, the battery light was staying on when when the key was removed, and the battery would drain(I have seen this before on other cars with faulty ignition switch). I disconnected the battery and charged it. Today I installed the new parts and the starter is not getting power. I tried the old switch and same issue. I tried a known good used switch and same story. I can start the car by energizing the starter directly. Also tried unplugging the alternator, and it does make the battery light turn off, but still no ignition. What should I look at next?
