[corrize]

Hello, on a Fuji camera, on the board of top command buttons and flash, at the input part of power, there is 3 components (black with square spot), they look like fuses, but on all 3, I measure resistances : 3K, 150K… They are not like the fuses : ok (0 Ohms) or burned (open).
Do you know what it is please ?
