Another speedometer fault question
1992 Z-28. The speedometer stopped working. Verified the speed sensor output to ECM - 7 vac. Research indicates a failed Circuit Board.- waiting for a new 3.9 ohm resistor and a Capacitor to arrive. Read an article about bench testing the speedo using a 9 volt battery. No explanation on how to test the Speedo Servo/Motor. Any ideas on how to test?
