Total Electrical Shut Down

Good Morning everyone. I have a 1995 525i which has completely shut down electrically. I was experiencing problems with my alarm system locking the engine, and my alarm expert advised that it was due to bad battery. So, I replaced the battery with a new one, and now, nothing! The alarm system bliking light won't even blink. No lights, no sounds, NOTHING! Does anyone have an idea? Is there a master fuse or something that could have blown? Thank you inadvance for your kind advice...fowcpa Also, this is the second new battery that I installed. The first may have been defective although in retrospect, probably was not. I also took a battery from a Lincon Navigator which was running at the time. Still, no electrical activity what so ever. Thanks...

There is a fusible link by the battery

thank you Sir! I am aware of the fuse, it is a30amp, and appears to be in good order, however, I will replace it now. Thanks again.fowcpa PS...I checked and replaced the fuse...it was a 10 amp fuse...NOTHING RESULTED.

Use a multimeter and Ck first for continuity before replacing it .

And you checked the in-line fusible link that runs along the positive battery cable ?

thank yuo, yes, it think so. there are so many little wires in there. one comes out of a cluster near the positive red terminal. The Positive red terminal dissapears into the bulk head under the seat. However the little red wire going to the fuse goes back left across the vehicle. The BMW alarm module was unplugged as the green male connector could not reach from the battery area across to the alarm cpu which was mounted by two screws on the left (driver side) rear under seat.

Thanks gentlemen, I have located and opended the fusable link in the battery compartment under the rear seat. However, all appears to be in order. There isn't a fuse as I recognize them. Perhaps a small chip of some sort. Is this what I am looking for? Thanks Bud Wilder

follow the link that paperplane put up .

Thanks a lot. Could please tell me exactly what i am looking for. The inside of the fusable link looks normal. Will a burn link look burnt? Like a typical blown fuse? Thanks

Thanks everyone. please note that I have a 1995 525i T. I have found the fusable link in the battery compartment. It looks normal, not fired. I am unable to find a link under the hood. The photos show a 535i, with link on the passenger side as you can read the bmw logo on the engine. There is nothing like that on this vehicle. One would think that a fuse should be in the "FUSE BOX"...however BMW in their infinite wisdom chose to hide elsewhere. Thank you in advance for your kind assistance. Bud

The best way to test it is with a multimeter, but you can also use a cheap test light.

Follow the smaller gauge wire coming off of the batt. pos. terminal. If there is no Fusible link, then theres no fusible link.

Thank you Paperplane, I finally caught a ride to Walmart & purchased a professional multimeter. I am disabled, so it has taken me a while. I have a 12.45 v hot battery, and same behind the fusable link inthe battery compartment. The red line beyond the link goes under the back seat into the bulk head. Ther is no power on the Postive jump post inside the engine compartment. Please if you have any further suggestions, please advise me. Thanking you once again, I am, Bud Wilder 1995 BMW 525i Total Electricial Failure. Peace...

hey Bud , check that new battery that you put in and tell me how many volts does it have right now . Just wondering if you got a defective one .

Thank you Paperplane. I purchased a multimeter PRO from Walmart. The Battery is hot, the RED cable is hot beyond the Fusable Link in the battery compartent. The Positive Post under the hood is dead. All of the fuses in the fuse box look good, but are also dead. There must be another fuse somewhere, can you please advise me. I am disabled, and have limited funds. thank you for your assistance. Bud

Sorry Bud but what my car shows is just the fuseble link . That would cause that . Hey bimmer gurus feel free to jump in with any info about the OP problem

maybe this is an EWS problem?

OK OP, you are getting absolutely nothing when you turn the key to pos. 2?

If there is zilch then its prob not EWS, check all grounds. From the batt to the chassis and chassis to motor.
Then follow the red positive cable past the fusible link and see where it goes. When I said check the fusible link I meant a continuity test, but if you are certain its fine then proceed to follow the wire. The wire should go out to the alternator and starter though I am not certain.

PS..the voltage reading on the Positive Jump Post in the engine compartment is .04 volts for what that is worth...Peace...Thanks...Bud

Well it might help if you have a good battery, though i am not certain.












Laughing Out Loud

However, you failed to read my prior post, this is the third battery that I have tried in this sucker...reading 12.47 volts at the battery, and 12.6 behind the fusable link...Thanks fow
