GROUND CIRCUITS

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 W.
•
System/power supply grounds: Check continu-
ity between terminal pins 7, and 8 of EMM con-
nector and the main harness ground.
•
Injector circuit grounds:
between terminal pins 7 and 8 of the EMM con-
nector and the main harness ground.
•
Sensor circuit grounds:
between terminal pin 29 of the EMM connector
and the appropriate sensor ground connections.
Refer to wiring diagrams.

IMPORTANT:
Repeat failures of fuse could be
the result of faulty connections or accessories.
The 12 V accessory circuit (purple wire from ter-
