On the way home today my tach and speedo stopped working. My blinkers also stopped working from the switch, but work if I use the hazard button. I dont have a clue as to what the problem is because its dark and I cant really do anything til morning. Please help ASAP, I cant afford much down time. TIA

i know the speed-o is fed from the speed sensor on my series 1. i think yours is the same. and the tach signal is fed from the icm.
they both went out at the same time?

i currently sorta have the same problem. my speedo, tach and oil pressure gauge still work, but my fuel, temp, and battery gauges are broke!!!!
i contacted ed morad about getting a new cluster, but he said that he currently out of them.

The only things that I can find in common are: the ign1 fuse in the rear fuse block, and ground 201 which on the passenger side interior foot well area, I believe behind the kick panel. Interestingly, the hazards use the same power and ground as the turn signal.
