Replacing fuses
- Turn off the ignition and disconnect the electrical device from the power source.
- Find the fuse corresponding to your receiver in the tables below.
- Remove the appropriate cover.
- To remove the purple plastic holder, pull it out of the fuse holder by the thin side.
- Remove the clip from the back of the fuse cover.
- Remove the blown fuse with pliers and replace it with a new one of the same amperage.
If the new fuse blows after a short time, have the electrical installation checked by a specialist workshop as soon as possible.
Attention!
Never repair fuses or replace a blown fuse with a higher amperage fuse. This can damage the electrical system. Fire hazard!
