General Information
This instrument utilizes a single LCD to display odometer and two trip odometer mileages. Press the Trip button on the dial window to cycle between odometer,
Trip 1, and Trip 2 displays on the LCD. Pressing and holding the Trip button for more than 2 seconds while viewing either Trip display will reset the trip currently
being displayed. The odometer cannot be reset.
NOTE: The odometer on the speedometer portion of this instrument will show some mileage less than 5 miles (8km).
This is a result of factory testing to ensure optimum quality.
TIP: Auto Meter always recommends performing the calibration process for best speedometer accuracy.
Speedometer Senders:
The electronic speedometer in this instrument is designed to operate with an electrical speed sender. The speed sender signal range must be between 500
and 400,000 pulses/mile (310 and 248,500 pulses/km). Any speed sender or electronic module that meets the following two conditions can be used:
1. Pulse rate generated is proportional to vehicle speed.
2. Output voltage within the ranges listed below:
a. Hall effect sender, 3 wire (5 to 16V)
b. Sine wave generator, 2-wire (1.4 VAC min.)
c. 5v Square Wave (CMOS)
Recommended – Auto Meter Hall effect sender, 3 wire, 16 pulses/revolution

INSTALLATION INSTRUCTIONS
DIGITAL TACh/SPEEDO COmbO
Installation Tips
1. A 12 V power source MUST be used to power this speedometer. A 12V motorcycle battery is a good alternative for cars without batteries.
A battery with minimum 5 amp hour rating is recommended.
2. Wherever possible, solder wire connections and avoid crimp-type connectors. This will minimize loose connections that could cause problems later.
3. Make sure you have a good ground to engine and battery negative terminal.
4. Wire installations should be neat and tied down to prevent tugging and fraying of wires at connections.
