What is overlooked most of the time is poor grounding or bad or dirty conections at the battery or the B terminal on the back of the Alternater, A clue you gave about the radio resetting is telling me a loose conection somewhere on your battery cables. Try adding some extra ground cables to the engine and fender. An overworked regulator will burn out early due to the heat from any resistance in the wiring.

Hi;
My name is Cliff-an old Ford mechanic. #1.check the wiring plug in at the alt. pull slightly on the wiring at the plug in to see if you have any loose connectors also check plug in wiring for any sign of (GREEN) corrosion. Next check BOTH ends of each battery cable and make sure they are CLEAN & TIGHT. Next check that you have a GOOD ground from the eng to the body. You should have approx 14.2 volts at the battery with the eng at 1000 rpm and a good load on the system, headlights, blower motor on high,wipers on.
Let me know what you find out.

Two years mine, no problem except ignition locked up a year ago. But tonight... tried to start it... ignition key turned, but engine wouldn't turn over... very faint click, no dash lights but map lights and dome light worked (bit faint). I wanted to push car out of parking spot to get a boost, but couldn't even get the transmission (auto) into neutral (locked in park). CAA arrived and used an "Eliminator" to boost, car started fine. I headed home (20 mins, highway speed). Everything seemed fine. About 2 mins from home, some of the dash lights came on, car seemed to sputter a bit, but didn't stall. I pumped the gas a bit, car responded. At a stop light, I put into neutral and rev'd, car responded. Dash lights went back to normal (none on). Once home, switch off, and tried to restart... nothing. Remote Key Entry will unlock driver door, no other doors... and won't lock anything. I had to use the key to lock doors. Hatch (stn wgn) won't lock. Tomorrow, I'll check cables to battery for corrosion, check connection to alternator and check ground. Any other thoughts? Where is the GEM ?

Is it only a coincidence? by janestahl

Two weeks ago, my daughter took my 2006 focus zx3 to the local ford dealer to replace a right rear turn light bulb. The next day the battery light came on. The problem seemed intermittent, so she neglected to take it to the garage. Last Friday she picked me up from work and during the 25 mile drive, the lights gradually dimmed, the cd player quit and then the radio came on by itself. We made it home just as everything died; power steering, brakes, everything. I had it hauled to the dealer who took two days to replace an alternator and battery, but that's another issue. My question is this: Is the fact I started having electrical problems right after they replaced a bulb coincidence or could the service department have caused the problem, either accidentally or deliberately?

that is some thing you could never prove. it is some thing that must be put down to coincidence unless you could PROVE otherwise which I think would be impossible.

Don't think so unless the car was jump started incorrectly at the dealership (crossed battery cables) for some reason. But if the car was started and running normally, they would have had no reason to do that. You can't damage an alternator by replacing a bulb.

2 things to check, 1. both ends of battery cables must be clean and tight. 2. grab wires at alt plug-in and give a slight tug and look for any signs of corrosion at the wire ends in the plug-in.
 
Also, changing a stop light bulb in no way had anything to do with your other problems, just bad timing.
