1985.5 Tach & Speedometer


Vehicle Information: Model(924/944): 944; Year: 1985; Engine (type, size, modifications): 2.5 Liter; Total Mileage: 32,000;

The speedometer and tach have hesitated to work about the last ten years. A simple tap on the dashboard has brought them working again. However, after not driving the car for a few months the tach will not come up along with the gas mileage indicator. The speedometer works. I took it to Dash Electronics and they cannot find anything wrong with the cluster. The connections leading to the panels seem to be OK and I cleaned them. Voltage seems to be OK at the connectors. How do I check for a signal input? Or do you have any other suggestions? Should I send the cluster to Hollywood or Palo Alto Speedometer for a more extensive check?
