JesseRaymond 0 Report post Posted April 16, 2013 The biggest worry each of us have is breaking down in the middle of the night. Fortunately we all brought the right brand of car to minimize the chances (:. However last night my nightmare came true. After a mate came and towed me home i diagnosed it to be a fault with my alternator. It wasnt charging the battery so the car died. My plan of attack is to obviously just replace it. My e30 is a m10 4 cylinder motor and i was planning on replacing my alternator with my parts car which is a 1990 m40 (unsure) 4 cylinder e30. If anyone has any previous experience of weather the alternator would fit my car or any advice would be appreciated! Thanks, Quote Share this post Link to post Share on other sites
