Thank you everyone for putting up with me. Here is my next issue:
When I turn off the key, there is no power going to the clock and the radio. When I turn the key "on", 3 volts goes to the radio and the clock.
This means that every time I turn the key back on, I have to unlock the radio and reset the clock.
The schematic is not very easy to follow (especially if you don't speak or write German). Does anyone know where the source of 3 volts is for these two systems? For some reason, the 3 volt signal goes away with the key "off".
