GENERAL CONCEPTS OF ELECTRICAL TROUBLESHOOTING
THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING PROCEDURE ON THE VEHICLE, CHECK
THAT THE BATTERY VOLTAGE IS ABOVE 12V.
CONNECTOR CHECK PROCEDURE
The procedure includes the following checks:
1. Observation and check of the connector position
on the component or on the coupling connector,
making sure that the locking catch is released.
2. Observation of the terminals on the connector:
no rust marks or dirt should be present and it is
important to check terminal correct positioning on
the connector (i.e., all terminals aligned at the
same depth) and terminal integrity (i.e., that termi-
nals are not loose, open/bent, etc.). For connec-
tors whose terminals are not visible (e.g. Marelli
control unit) use a metal cable of suitable diameter
and introduce it carefully in the connector slot at
the same depth as for the other terminals of the
connector.
CAUTION
IN CASE OF TEMPORAL MALFUNCTIONING,
CARRY OUT ALL DUE CHECKS LOOKING FOR
FAILURES BY MOVING SLIGHTLY THE CABLE
HARNESS BEING INSPECTED.
3. Pulling the cables slightly from the back of the connector in order to check the correct position of the
terminals on the connector and of the cable on the terminal.
CONTINUITY check
Check goal: this control is to check that there are not any circuit interruptions nor excessive resistance,
for instance caused by rust, on the two terminals being inspected.
