Tachometer Help
Hello! A month into my first e30 (1991 318i manual US, which does originally have an m42 it’s not swapped look it up), and the tachometer hasn’t worked since I owned the car. I do not know why it doesn’t, but I needed to replace backlighting in the cluster so figured I’d check the SI board and the batteries while I’m here. All of my cluster works fine but the tachometer.
Don’t know what I’m looking at here, does anyone have advice on what to do here? Order of components to test/check if they’re the issue? Do I go pin to pin and check solder? Also the batteries look fine to me. Not sure the SI board was the place to start. Anything helps…
BONUS: if anyone has broken an ear off the cluster when removing it and could share how they fixed/managed it that would be welcome.
