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
of circuit tested. Continuity may also be tested by setting the tester selector to the "Ohm" symbol and
checking that the resistance in the circuit is zero or of a few tenths of an Ohm.
IMPORTANT: THE CIRCUIT MUST BE UNPOWERED DURING THIS TEST. IF THE CIRCUIT IS
POWERED, THE RESULTS OF THIS TEST ARE MEANINGLESS.
Checking GROUND CONNECTION
Purpose of check:
the purpose of this check is to verify that a cable or circuit is correctly connected
to the ground (-) of the vehicle.
Tester: set the tester selector to the "continuity" symbol and place one of the tester probes on the vehicle
ground point (or on the battery negative pole) and the other probe on the cable under inspection. Nor-
mally, the tester will sound an audible signal to confirm continuity in the section of circuit tested.
Continuity may also be tested by setting the tester selector to the "Ohm" symbol and checking that the
resistance in the circuit is zero or of a few tenths of an Ohm.
IMPORTANT: WHERE GROUND IS PROVIDED BY THE ECU, CHECK THAT THE ECU IS EFFEC-
TIVELY PROVIDING THE GROUND CONNECTION FOR THE CIRCUIT DURING THE TEST.
Checking VOLTAGE
Purpose of check:
the purpose of this check is to determine if a cable is carrying voltage, in other
terms, to verify whether it powered by the battery or ECU.
Tester:
set the tester selector to the "DC voltage" symbol and place the red tester probe on the cable
under inspection and the black tester probe on the vehicle ground point (or on the battery negative
pole).
