2000 Mazda Protege 4 cyl Two Wheel Drive Automatic 90000 miles
My battery light was on and I was told I had a bad alternator. I switched it out and everything seemed Ok and the light went off. Two days later the light comes back on. I take it to the shop where I purchaed the alternator and they test it while the vehicle is on and they say they can't get a reading off the alternator. They ask me take it off and return it. After removing the alternator they check it in their machine and it passes with flying colors. My battery is also fine as far they can tell. I don't know why the alternator would not register on their gauge. Could it be a a fuse causing the light to go on? Could the battery not have enough charge? Is one of the lines from alternator to the battery bad? If so how can I test that. I thank you for your help and let me know if you need any more info.
