EXHAUST WATER
VALVE TEST
Disconnect electrical connector from water valve
solenoid. Use an ohmmeter to measure solenoid
resistance.
SystemCheck CIRCUIT
TESTS
Make sure the SystemCheck engine monitor can
warn the operator during a “NO OIL,” “WATER
TEMP” or “HOT,” “CHECK ENGINE,” or “LOW
OIL” condition. Check the condition of the warning
system and associated wiring and connections.
Test the engine monitor regularly and anytime you
suspect an alert situation has been missed.
The instrument harness must be connected to the
outboard before performing the following tests.
Refer to the Engine Wiring diagram and the
MWS Instrument Wiring diagram in the back of
this manual.
IMPORTANT: Use jumper wires made with the
appropriate terminals to test the warning circuits.
Gauge Self-Test Check
Turn the key switch to ON with the outboard NOT
running. The gauge warning lights for NO OIL,
WATER TEMP, CHECK ENGINE, and LOW OIL
must all light at once, then turn off in sequence,
and the warning horn must sound for one-half
second.
If the gauge lights do not turn on, turn the key
switch OFF. Disconnect the gauge 8-pin connec-
tor from the back of the gauge and turn the key
switch ON. Test for battery voltage between
