GENERAL NOTIONS FOR TROUBLESHOOTING ELECTRICAL FAULTS
THE SECTIONS RELATIVE TO THE ELECTRICAL SYSTEM CONTAIN DRAWINGS OF CONNEC-
TORS; NOTE THAT THE DRAWING ALWAYS DEPICT THE CONNECTOR/COMPONENT VIEWED
FROM THE WIRING HARNESS SIDE, I.E. FROM THE SIDE ON WHICH THE CABLES LEADING
FROM THE MAIN WIRING HARNESS ENTER THE CONNECTOR/COMPONENT.
CAUTION
BEFORE STARTING ANY TROUBLESHOOTING PROCEDURES 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 correct
position on the component or on the coupling con-
nector, making sure that the locking catch is re-
leased.
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 THE CASE OF SPORADIC FAULTS, MOVE OR WIGGLE
THE RELATIVE WIRING HARNESS SLIGHTLY WHILE PER-
FORMING EACH OF THE CHECKS INDICATED FOR TROU-
BLESHOOTING.
3. Pull cables gently from the back of the connector to check that the terminals are fitted correctly on
the connector and that the wires are fastened correctly to the terminals.
Checking electrical CONTINUITY
Purpose of check:
the purpose of this check is ensure that there are no interruptions or excess re-
sistance (due to corroded terminals, for example) in the circuit under inspection.
Tester:
set the tester selector to the "continuity" symbol and place the probes of the tested at the two
ends of the circuit. Normally, the tester will sound an audible signal to confirm continuity in the section
