Speed Sensor Test

Disconnect sensor wires from amplifier and connect an ohmmeter between the wire connector terminals (green & black). A reading of approximately 400 ohms should be obtained. If ohmmeter records 400 ohms and speedometer operates properly, speed sensor is probably good. A new sensor can also be substituted in place of old sensor to check for proper operation.
