Tips for changing relays and fuses

Relay overview

Change relay

Disconnect the battery to prevent discharge and short circuits
Carefully loosen stuck relays, e.g. with a small lever
Function test by cross-swapping with an identical relay
If successful, insert the new relay; otherwise reinstall the old relay and reconnect the battery

Overview of fuses

Change fuses

Always replace with a fuse of the same amperage (color)
If a fuse blows again, there is a short circuit – find the cause.
Use tweezers for removal to protect terminals and adjacent fuses.
