I have a 2005 Ford Focus in the repair shop right now for an alternator problem. Our problems started about two months ago with the car acting up not starting, or when idling the dash goes crazy with lights going bright or weak and various electrical components not working such as headlights, radio, ect. We replaced the alternator for the 3rd time with another autozone warranty alternator and it lasted about two weeks. The NAPA repair facility thinks it is due to cheaply made autozone alternators and we are now installing a good quality Bosh alternator which was about $330. The battery was replaced last year. I had them check the pigtail connector to the alternator as other post I had read had found that the inside of the pigtail had serious corrosion in it that can create high resistance and poor grounding connection with the alternator and end up causing diodes inside the alternator to fail and burn up your battery. The diodes are responsible for converting the current from A/C to D/C and there are six of them in sets of two. He said the diodes are the most common thing to fail inside the altrnator and casing huge fluctuations in the current to the battery and the car wiring. We are picking up the car tomorrow and I will post back how everything goes over the weekend since this is a company vehicle we use a lot. It has 80,000 miles on it. So, this is alternator 4 in a year but the first highend one so we will see if that makes a difference plus it will now be under NAPA warranty if it fails.

NAPA does have a point about the quality of chain-store rebuilds. Alternators are rebuilt from random reconditioned parts. They don't rebuild each one using all its original parts. So if the process is rushed or they cut corners, quality control goes downhill fast.

I have a 2004 Malibu and a 2005 Freestyle with the overheating bulbs. My solution was switch to led bulb. It flashes faster, but it eliminates the meltdowns.

There are after-market light suppliers such as Keystone lighting and you may also NAPA for these assys. Good luck.

Im thinking its the ignition switch as well. It always turns over but doesnt fire, cold or warm and it happens about 90% of the time and light issues are about 95%. Im changing the spark plugs and fuel filter today and will see if that helps it start. if i turn the ignition on and off without starting the car i can eventually get lights back. the odd thing is i have no other electrical or dash issues. jsut lights and starting. im also going to check the light wires witha multimeter to see if theres power going to them when they dont work to know if its a connector issue or a break or fuse.
**just a tip for all focus drivers who think 300 kms per tank is ridiculous. the permanent air filter on the car is NOT a permanent filter. i switched mine out for a cold air intake which cost me $30 and fits right on the old pipe where the old airbox was. No modifications necessary all sensors stay where they are and i now get 600 kms per tank and have better response. **

You can try this, remove the plug wires and insert a phillips screw driver in each plug wtre, and hold shaft of phillips about 3/8 " from ground and have a friend crank over eng and watch spark . If no spark, check crank-posistion sensor. should be mounted at 10 or 2 oclock pos. above front crank pully. these have been known to go bad at times .

Well problem with the lights is fixed. It turned out to be a severely corroded relay. And i replaced the spark plugs yesterday and its runnning way better. Just wondering tho, Does anyone elses spark plugs read that the engine is running hot? All four plugs were completely white. I put in new ones and made sure their gapped correctly. And so far no hesitation, or surging and the car feels looser.
Next question, Im replacing the fuel filter this week and just wondering if anyone knows which fuses i should pull as theres like 5 that are assigned to fuel.
Thanks for the help!
