Speed Sensor
- Disconnect 6-way connector at amplifier, and connect an ohmmeter between wire connector terminals (Dark Green dashed and Black on Van models, Dark Green/White dashed and Black on all other models) at speed sensor end. A reading of about 40 ohms should be obtained.
- A reading of 0 ohms indicates a shorted coil. A maximum reading indicates an open coil. Replace sensor in either case. If reading is 40 ohms and speedometer operates properly, speed sensor is probably good. A speed sensor of known quality can be substituted in place of existing sensor to check proper operation.
