Fuse box diagram (fuse layout), location, and assignment of fuses BMW 7-Series (E38; 728i, 728iL, 730i, 730iL, 735i, 735iL , 740i, 740iL, 750i, 750iL, 725tds, 730d, 740d) (1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001).
Checking and Replacing Fuses
The wiring circuits in the vehicle are protected from short circuits by fuses. This greatly reduces the chance of damage caused by electrical problems.
To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.
Note
- Before replacing a fuse check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
- Never attempt to repair a blown fuse, and do not replace a defective fuse with a substitute of another color or amperage rating, as this could lead to a circuit overload, ultimately resulting in a fire in the vehicle.
- If a fuse blows again contact a qualified service center.
