944 Turbo Tachometer is not working.

Any assistance in trying to fix would be appreciated.

Thanks.

Since the car is running, the signal from the ECU is probably OK.

That narrows it down to a bad tach (it does happen) or a broken wire (maybe) or a loose connection (most likely). Get out a wiring diagram ahd start checking.

There are also bench test procedures for the tach, but you need a signal generator and a 12 volt power supply...

Thank you.

I face the same issue (sort of - intermittently working tach). My attempt to replace capacitors failed when I tried to reassemble (broke the pin that is connected to the needle).I didn’t feel the repair cost of $400 was reasonable from either of the often mentioned speedo repair places.

I spend weeks looking for a good one on eBay US, but finally found a good selection a couple of months ago on eBay UK via seller luxury_car_spares.

Pricing was reasonable.

Check the connector under the dash passenger side. 8pin flat connector I think. That's the most likely location of the failure.
