TESTS
Make sure the
SystemCheck
engine monitor can
alert 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
instrument harness terminal 1 (purple wire) and
terminal 2 (black wire).
•
If battery voltage is present, replace the gauge.
•
If there is no battery voltage, check that 12 V is
present at terminal “B” of the key switch. Check
condition of the instrument harness, key switch,
and connections.
If the lights worked, but the warning horn did not
sound for one-half second, turn the key switch
OFF. Disconnect the warning horn 2-pin connec-
tor. Substitute a known good warning horn. Turn
the key switch ON.
•
If the substitute horn beeps, the original horn is
defective and must be replaced.
•
If the substitute horn does not beep, check for
battery voltage between instrument harness 2-
pin connector, terminal 2 (purple wire) and
ground with the key switch ON. Also, check the
tan/blue wire for continuity between pin 8 of the
8-pin connector and pin 1 of the 2-pin connec-
tor.
•
If battery voltage is present at the purple wire
and the tan/blue wire has continuity between
