OBSERVATION
Oil tank level does not display.
Engine water pressure does not
display.
Water pressure faults after initial
setup.
ICON instrument display is erratic.
Gauge repeatedly reset to factory
defaults.
136
POSSIBLE CAUSE
Requires input from oil tank sender.
Requires input from a water pressure
transducer.
Water pump is faulty.
The block-mounted water pressure sen-
sor is not connected to the engine EMM.
The NMEA 2000 network water pressure
sensor is not configured properly.
Engine EMM is not correctly configured
for the water pressure sensor.
Power supply battery voltage is less than
12.5V.
One or more terminators are missing
from the NMEA 2000 network.
If this occurs during heavy power use,
possible poor battery condition exists.
PROCEDURE
Each oil tank uses an outboard position-spe-
cific converter.
If using a block-mounted water pressure trans-
ducer, use Evinrude Diagnostics software to
set EMM.
Verify operation of water pump.
Check the connection for the block-mounted
water pressure sensor at the engine EMM.
Replace the NMEA 2000 water pressure with a
known good component.
Use Evinrude Diagnostics to verify the water
pressure sensor setting.
Check for a minimum 12.5V across the termi-
nals of the power supply battery.
Check for installation of two terminators on the
NMEA 2000 network. Check network buss
cable and device connections.
Check system supply battery voltage with
engine running. Check Ignition and Ground
connections on pins 4 and 5 of the tachometer.
