CHECKING OF BULBS
2.Check for continuity at the bulb terminals.
*****************************************************
Checking steps:
●
Set the pocket tester selector to “
Ω
×
1”.
●
Connect the tester leads to the respective
bulb terminals. Take for example a 3-termi-
nal bulb as shown left. First check the conti-
nuity between the terminals
1
and
2
by
connecting the tester (+) lead to the terminal
1
and the tester (–) lead to the terminal
2
.
Then check the continuity between the termi-
nals
1
and
3
by connecting the tester (+)
lead still to the terminal
1
and the tester (–)
lead to the terminal
3
. If the tester shows “
∞
”
in either case, replace the bulb.
*****************************************************
3.Check the bulb socket by installing a proven
bulb to it. As in the checking of bulbs, con-
nect the pocket tester leads to the respective
leads of the socket and check for continuity
in the same manner as mentioned above.
