Fuse Holder And No-Fuse Breaker - Robin LG072 Service Manual

9 - 5 FUSE HOLDER
and
NO-FUSE HOLDER
9 - 5 - 1 FUSE HOLDER
Check that a fuse is in the fuse holder and check its conti-
nuity with a tester. (See Fig. 9-6.) If it carries current, it is
normal.
FUSE HOLDER
If there is no current, take the fuse out and check it for
continuity. If the fuse carries current, the fuse holder is
faulty. If the fuse carries no current, replace it with a fuse
of the correct capacity, and check the fuse holder again for
continuity.
Fuse capacities are shown in the table below.

"LG301, LG301 D employ a no-fuse breaker.
Table 9- 7
9-5-2 NO-FUSE BREAKER
Only the LC301 and LG301D have a no-fuse breaker.
Push the power switch off and check continuity. If no cur-
rent flows, it is normal. Then push the power switch on and
check continuity again. If current flows, it is normal.
If the breaker is a two-pole type, the two pairs of terminals
must carry current.
