- Disconnect 6-way connector at amplifier. Connect ohmmeter between Dark Green and Black ("E" series) or Dark Green/White (Bronco and "F" series) and Black connector terminals at speed sensor. A reading of about 200 ohms should be obtained.
- Replace speed sensor if not within specification. If reading is 200 ohms and speedometer operates properly, speed sensor is probably good.
