Fuse box diagram (fuse layout), location, and assignment of fuses and relays Alfa Romeo GT (Type 937) (2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010).
Checking and Replacing Fuses
The fuse is a protective device for the electric system: it comes into action (i.e. it cuts off) mainly due to a fault or improper action on the system. When a device does not work, check the efficiency of its fuse. The conductor element must be intact; if not, replace the fuse with one of the same amp rating (same colour).
Note
- Before replacing a fuse, make sure the ignition key has been removed and that all the other services are switched off and/or disengaged.
- Never replace a fuse with metal wires or anything else. Always use an intact fuse of the same colour.
- Never replace a fuse with another with a higher amp rating; DANGER OF FIRE.
- If a fuse blows again, contact an Alfa Romeo Authorised Service.
