Note: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a normal installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an output on a circuit different from that to which the

Panel
Mounting
The instrument panel must be 3mm to 19mm
(1/8” to 3/4”) in thickness.
• Drill a 51mm (2”) hole in the instrument panel.
• Remove brackets and insert the instrument so
the back is flush with the instrument panel.
• Slide the bracket over the instrument and

Wiring Connection
• Keep electrical and transducer cables away
from alternator or other noise generating
electrical cables. Avoid connecting the
instrument to power circuits that share loads
with ignition, alternators, inverters and radio
transmitters. Electrical power supply
connections should always be as short as
possible.
• Connect the red wire to the positive supply via
a 1 amp fuse or a 1 amp circuit breaker.
Connect the black wire to the electrical ground.

4 PIN
CONNECTOR
• Connect the 4 pin Fuji connector to the speed
and temperature transducer cable connector.
Extension cables are available if the
transducer cable is too short.

Appendix B - Troubleshooting Chart
No display:
1. Check DC power connections and DC polarity with voltmeter.
2. Check fuse.
No speed or log readings:
Check and make sure that the paddlewheel on the impeller is not
stuck or fouled with growth.
Inaccurate speed readings:
1. Re-calibrate
2. Check paddlewheel
Erratic speed readings while moving:
1. Check to make sure that the impeller is aligned fore and aft.
2. Review the installation for possible erratic water flow over the impeller.
Erratic readings only while engine is running:
1. Re-route power and transducer cables away from engine, ignition
wires and battery cables.
2. Add feed-through filter capacitor on the positive terminal of the ignition
coil.
3. Add an alternator whine filter to alternator.
4. Replace spark plug wire with resistive type.
No temperature reading or is inaccurate:
1. Check calibration.
2. Check for break in cable.
Simulation mode:
At power up, if all the segments display for 5 seconds then the
instrument is in simulation mode.
