is found, check wiring and terminals on
key-switch and battery.
•
Repeat the same procedure with the
ends of the tester inserted between
contact 5 (+) and 6 (-) and check the
presence of the battery voltage with the
key switch at on. If this does not hap-
pen, check the regulator's ground ca-
ble.
•
If the checks given above are unsuc-
cessful, jump pins 5 and 7 on the con-
nector, turn the key-switch onto ON
and turn the turn signal switch alter-
nately from left to right to visualize the
continuous operation of the lights (as
powered directly by the battery). If the
lights do not go on, check the switch
and its cable, if these are not damaged
or faulty; replace the regulator as defi-
nitely faulty.

Dashboard check light does not go on. Detach the
connector to the voltage regulator.
•
Apply a tension of 12V to the pin
marked with the number 5, check, us-
ing the digital tester; there is an equiv-
alent output (12V) from pin 3 for at least
5 seconds.
•
If pins no. 4 and/or no. 3 give no output
voltage, replace the regulator.
•
If pin no. 3 gives output voltage, check
the system and the low-oil or low-fuel
warning lights.
