2002 BMW 325i
Pull the panel from behind the battery and see if you have blown the main 250A fuse.Hello, i bought a 2003 325i, and about a week in I attempted to replace the alternator, but my genius friend did not disconnect the battery as we lifted the old unit out, and I ended up seeing sparks fly, now with the new or old alternator, the car does not get charged. I have checked all of the grounds that would be related to the issue, but none seem bad and I don't think the short would effect a ground. I need to know if the starter links the alternator to the battery, or a fuse or relay, because whatever it is, I fried it for sure. Car will run only when jumped, and dies instantly once the starter cables are removed. I cannot seem to figure this one out with out help so I am going to need some recommendations from you guys. I know it is not the battery for sure, and I know it is not the alternator its self for sure because I swapped it back with the working one. Thanks for any help.
