c.robertson00 11 Report post Posted December 16, 2008 My e30 wont hold charge in its battery. Ive tried 3 diffrent batterys and they all go flat after about a week. I replaced the brushes on my altenater and it has been fine for about two weeks up untill yesterday. I gave it a bump start today and took it for a good 20 minute drive. I then came home and turned it of and started it up agin and it turned over 1st pop, I then came bak 30 minutes later and it had nothing. Does it sound like a crook altenater or something else?

bravo 35 Report post Posted December 16, 2008 That'd be my first guess. You can save alot of time and money by just going to an auto sparky and paying them to run their test gear on your vehicle - will be cheaper than buying $$$ of new parts to find out you havn't fixed the problem.
