Ok, last night I started on this project, rebuilding Bosch ignition box. My box has been acting strangely always, sometimes it just dies and starts to keep this "strange" whining noise, irregular one. If you hit it, it works and starts to whine normally.
The cursed box left me in middle of road in center of the city where I live. Guess how humiliating that was.
It was time to do an operation. -> Replacing all the resistors, 30 year old condensators, and put new transistors in place. There are other components on the circuitboard that are not recognisable, but can't help with those.
Here are some picture of the disection:
