GROUND CIRCUITS
All ground circuits are essential to reliable out-
board performance. Make sure all ground connec-
tions are clean and tight. Refer to wiring diagrams
for specific wiring details.
EMM
Ground Tests
Disconnect the battery cables at the battery.
Use an ohmmeter to check continuity of ground
circuits. Calibrate the ohmmeter on the high ohms
scale. Resistance readings for all ground circuits
should be 0
Ω
.
•
System/power supply grounds: Check continu-
ity between terminal pins 5, 7, and 8 of
EMM
J2
connector and the main harness ground.
•
Injector circuit grounds: Check continuity
between terminal pins 14, 20, and 21 of the
EMM
J1-B connector and the main harness
ground.
•
Sensor circuit grounds: Check continuity
between terminal pins 26 and 27 of the
EMM
J1-A connector and the appropriate sensor
ground connections. Refer to wiring diagrams.
Additional Ground Tests
Check connections and continuity at the following
locations:
•
Starter solenoid terminal B and main harness
ground.
•
Trim and Tilt module ground at main harness
ground.
•
CPS connector pin 3 and main harness ground.
FUSE
The engine harness 12 V (B+) circuit is protected
by one automotive style 10 amp minifuse.
The fuse is located on the port side of the power-
head, in the flywheel cover.
IMPORTANT:
Repeat failures of fuse could be
the result of faulty connections or accessories.
The 12 V accessory circuit (purple wire from ter-
minal “A” of key switch) is often used to power
accessories.
