I need my alternator replaced on a 2004 Focus SE 2.0L. Is there a place with quality work at affordable prices in Round Rock to have this done? Replaced my battery. 1 month later I have to jump the Battery. Engine light comes on for a few days then goes out for a day. Does this continually. Took it to a shop because I thought the alternator might only be partially working as the engine idle seems to be unsteady at times. They said my battery would not hold a charge so the could not test it properly. I went to autozone with the shop printout. They tested the battery as good but replaced it anyhow as it was under warranty. Went back to the shop the next day, they said the battery had already gotten weak so I needed a new alternator. They want to charge me over 500 dollars to replace it.
