1. Turn Instrument power OFF, then ON.
2. For 2 seconds after powering up, the Instrument will show all 8s. During
This time quickly cycle the Totalizer Reset Switch from its’ run position
too reset and back twice. Leave it in the run, or off position.
Note: For 20 seconds, the four display windows show the following:
Hours Window: Alternates between the 3 digit software version,
(X.XX) and a 5 digit code number, (XXXXX).
RPM Window: Shows RED switch setting, (Refer
to tachometer calibration sheet).
GPH Window: Shows ARROW switch setting,
for Sensor model selected.
Gallons Window: Shows BLACK switch setting, (Refer to the Calibration sheet).
II. SUPPLY VOLTAGE and GROUND TEST
1. Measure voltage between the RED power wire on pin 9, and the BLACK Instrument ground wire on pin 5. __________VDC
This reading should be approximately 12 VDC, but not lower than 10 VDC.
2. If 12 VDC is not present, measure between the RED power wire on pin 9 and a known good ground in the
instrument panel. If you measure 12 to 14 VDC between the Red wire and ground, there may be an __________VDC
Instrument ground problem.
NOTE: Some applications use both pins 1 and 9 for Instrument power.
3. If 12 to 14 VDC is not present in steps 2 or 3, check wiring, switches, fuse, and the 12 VDC power source.
III. LED BACK-LIGHTING WIRING TEST
1. Measure voltage between the ORANGE, wire on pin 4 and the BLACK wire on pin 5, for 7000(0) and
8000(0) series Instruments. On 9000(0) series Instruments, measure between pin 4, and the
BLACK/ORANGE wire on Pin 12.
__________VDC
2. If 12 VDC is not present, measure between the ORANGE wire on pin 4 and a known good ground in the instrument panel. If
you measure 12-14 VDC, there is a power supply problem to pin 4, or a ground connection problem to pins 5 or 12.
IV. SENSOR(S) TEST
1. With engine(s) idling, measure and record voltage between the RED power and BLACK ground wires on the
Port Sensor. Voltage should be 12 to 14 VDC. ___________VDC
2. Move the voltmeters’ negative lead to the WHITE signal wire. With engine idling, measure and record the
voltage reading. Readings between 4 and 10 VDC usually indicate a good sensor. ___________VDC
3. Stop the engine while observing your voltmeter. Readings should fluctuate between a high of 9 to 12 VDC, and
a low of 0 to 4 VDC as the sensors’ turbine slows to a stop.
NOTE: This may not be seen on digital voltmeters. ___________VDC
4. With engine(s) idling, measure and record voltage between the RED power and BLACK ground wires on the
Starboard Sensor, (If used). Voltage should be 12 to 14 VDC. _________ VDC
