Did you get 13.7v when the car is idle?

Have you tried w/ higher engine RPM like 2000~2500? What is the voltage reading then? If you get higher voltage reading, it might just mean your alternator is a bit weak, but not bad.

If this is the case, you need to buy a battery charger, which is much cheaper than another alternator.

• 不難。找到tensioner，用扳手放鬆，卸下皮帶。翻翻前兩天的帖子，有人問過ford taurus. -寶驢車主- ♂ (0 bytes) () 01/05/2011 postreply 08:45:14
