Loss of Power

[Sueleeex]

I have owned a '98 528i Touring for almost a year and I have had a continual problem with a complete loss of power. It has been into the garage on numerous occassions and has had a fortune spent on it in the hope that the problem is fixed, most recently being a brand new alternator just last week. However, out I went the other morning and once again, nothing, no central locking, no lights absolutely nothing. we tried to jump it with my partners car but all we got was the lights, heating, radio etc, but no engine. We have tested the battery and that appears fine. Has anybody encountered any problems like this or has anybody any ideas?? Thanks

Fusible link
























Cost: Cheap

Difficulty:
Location of the fusible link in a 525i (Thanks to John T)


Bmw E34s have a big fuse right after the battery that protects the car electrical harnesses.

Failure syndromes:
• Intermittent simultaneous falure of wipers, sunroof, windows, central locking, radio...
• No power, like if the battery was dead.



525i Procedure
10mm wrench or socket.
New fuses.
1. Disconnect the battery.
2. Open the fusible link box.




3. Remove the 4 x 10mm screws and change the fusible links.





4. Installation is reverse of removal.

535i Procedure

535i fusible link from Gordon.

If the fusible link is ok, check the second fuse box under the rear seat and check the fuse that might be corroded (no. 37, 30 amp) which handles all of the central locking and the electric windows and sunroof.
