Wanted: SI board

[mentholguy]

Hello,

Does anyone have extra SI board for late model (89 325i) for sale?

Must be in fully functional condition.

Mine just gave up on me even though it was repaired before and been told it’s not repairable.

Thanks

How do you know when your SI board takes a dive? My cluster worked intermediately but now the mph does not work at all. Thinking its my board but I don't know the symptoms of a bad board.

Both my tachometer and mpg needles were jumping like crazy, then stopped.

Got new battery replaced, tachometer worked again.

But couple days ago, after I disconnect and reconnect the battery in the trunk, my tachometer isn’t moving at all.

Last time I sent my cluster out for repair, I was told that my SI board is not 100% repairable, and I think it just died on me.
