Speed Sensor (Electronic Speedometer)

Models with electronic speedometer do not use a separate speed sensor, but are connected directly to the speedometer itself. To test, raise and support the rear of vehicle so wheels can turn. Connect an AC voltmeter to the Dark Green-White lead and ground at the amplifier. With speedometer indicating 30 mph, voltmeter should read approximately 6 volts.
