Hi there, cluster on my e30 had an analog clock in it, I bought an rpm gauge and it does not work, all the electrics check out, SI batteries are on 3.2 V the coding plug is correct, and the gauge and the cluster are VDO and in the c101 connector i have black wire on pin 9. What else could be the problem, thanks?

Tachometer will not work without the coding plug. You will need that too. If your SI board is the original 30 year old board, consider it bad. Even if the batteries are 3.2v each, they output amperage is probably so low, they have no current to drive the SI board.Owner - Bavarian Restoration

If your batteries are the original 30 year old batteries, yes your SI board is dead.Owner - Bavarian Restoration
