My newly purchased 1995 525i died on me yesterday on the road. The Battery CEL went on first and then the rest of them. At a stop the RPMS dropped and it died. I jumped the battery and it started up and drove maybe a mile then died again. Now after jumping it it will move maybe 60 seconds before the tach turns off the engine stops reving and the car dies again. Alternator needs replacement? or battery? Whose got a link? Thanks guys!

 

Sounds like an alternator problem.

 

throw on a voltmeter when you have it running

 

Usually when the battery light goes on it's something with the alternator. Either the alt is up ---- creek, alternator belt is super loose or just ------- gone or the battery is just old.

 

You bought that shitty beamer?
Welcome to repair land
Voltmeter that ----

 

alternator turned out ok. Was the battery. Thank god. runs mint now. thanks nigs.

 

90% of the time a battery light is the alt. The battery could have took a ---- because it is not charging like it should.

 

Yeah, I always thought that if the alt was good, it will stay running.
