10.7 Changing a Fuse on the FC-FI
The FC-FI has seven user changeable fuses. See Table
13 for more information.
To change fuses, complete these steps:
1 Identify the blown fuse on the board visually or by
checking for continuity with a multimeter. Ensure
that the fuse is one of the user replaceable fuses
listed in Table 13.
2 Insert a screwdriver under the centre of the fuse and
pull it out.
3 Check that the replacement fuse is of the correct
current rating.
4 Put the replacement fuse on top of the connector,
taking care that the current number is facing
upwards, and press it down firmly.
