ELECLIGHT INSPECTION
7-9
When removing a bulb be careful to hold the
bulbholder or its housing firmly. Never pull the
cable, as it might detach from the terminal
inside the connector.
CAUTION:
WARNING
Keep inflammable products and hands well
away from bulbs when they are on (danger of
burns and fire). Do not touch the bulb before it
is cool.
2. Check the continuity between the bulb termi- nals.
▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼
Control procedure:
•Set the tester selector to Ωx 1”.
•Connect the tester terminals to the bulb pins.
Take, for example, a three pin bulb as shown
in the figure. First check continuity between
pins (1) and (2), connecting tester terminal (+)
to pin (1) and terminal (–) to pole (2). Then
check the continuity between poles (1) and
(3), again connecting tester terminal (+) to
pole (1), and terminal (–) to pole (3). If the
tester indicates “ ∞”, even in one case only, the
bulb must be replaced.

the bulbs, connect the tester terminals to the
respective socket cables and check continuity
as described.
