W126 LMO question

Hello together I have a question about my 300SE Jg. 87 because of the ABS. It’s like I’m not allowed to drive yet and the 126er doesn’t have a TÜV yet (comes in January), so I can’t say much information about driving or braking behavior. In all cases it was so that main father and I went on a bigger test drive 2 weeks ago, because we had eliminated all major technical defects. We then made about 80km/h a full brake and the rear wheels blocked! that?, actually not because of the ABS? And now we are at the next problem I have not checked the indicator light yet, however, fear that this is defective, because the hand brake control light is defective, which always lighted when I pressed the brake and suddenly it did not do so anymore, I suppose the ABS lamp is also gone. And now I come to the last question: If you turn on the ignition, should all the lamps light? I also have the ASD verba ut and this lamp doesn’t glow either, if the ignition is one, would that be right? With me, in general, only about half of the control lamps is that good? My manual for the car is on Italian and this I speak little to no at all…
