Alternator troubleshooting '95 TI, M42, manual, 208,000 miles. Symptoms: Idles kind of rough. Lopey sound, like a misfire. An intermittent grinding noise under the hood. Battery voltage at 12.95V when idling (Bentley says it should be 13.5 to 14.5). I'm pretty sure I need a new alternator, but I wanted to get a second opinion. Also, I see 70, 80 and 90 amp alternators for sale that all supposedly fit this car; how do I know which one I need? |
