I have an alternator on a 2004 ford focus that has been work intermittently, some days working perfectly charging around 14.7 volts with all accessories on, then some days (today) not doing anything. I pulled the alternator and battery, had both load tested at two different shops and both checked out as GOOD! Cleaned all of the connections and replaced the three wire plug to the alternator, then reinstalled. Drove the vehicle all day with no battery light, no issues. Today nothing! I have established that I do have continuity from the power cable to the positive battery post and ground. I'm wondering if this problem could be related to a bad internal regulator, brushes, or some other internal issue that could cause intermittent performance. I'd rather try a rebuild kit over replacement due to limited finances. Please HELP! Thank you.
