needing help choosing an alternator guys mines is cooked! will any cvh alternator fit in my 1989 mfi xr3i? i can get one of a 1.4 cvh at my local scrappy or if anyone knows where i can get one that would be better. i hooked up a sub/amp to my car and since then the car is lasting no longer than five mins jump started with the stereo off and the lights/fan on just goes dim and cuts out. battery is new so i assume its the alternator needing replaced as the belt is fairly new and tict! any help please many thanks
