I have a 2001 ford focus se.
My entire electrical system flickers and I look like a strobe light going down the road at night.
My headlights, dash lights, radio, air, brake lights, EVERYTHING electrical flickers completely off and on. MPH flickers and drops and I don't know how fast I am going, gas gauge flickers, RPMs flicker, the heat gauge drops and stays low... The heat doesn't really work sufficiently anymore. Even my engine kicks off briefly and my car jerks... NOT GOOD! All at the same time. When I use my blinker, heat, or even roll down my window... It particularly acts up like it's possessed by the exorcist.
I have had numerous wiring problems found on my car that have been corroded and severed such as ground wires and wires for the ignition plug (not sure if that is what it is called, but there are three wires that come out of the plug. the right wire when severed i learned makes your car run and sound like a lawn mower, the middle one severed just completely shuts your car down, and im not sure what the right one does when severed) that have corroded and snapped off. I've gotten the battery cables replaced, the ground wires fixed that were found completely snapped off, and to no avail. I've been told that it's the alternator, but the voltage has been checked 3 different times and that is fine. I've gotten other people to check it as well and I've had some wires that were apparently running too hot, but the wires looked fine and I am not sure if anything was done to fix that problem... At that point I was fed up.
Someone told me it is the voltage regulator, others say to just try and replace the alternator, but why the hell would I do that when it is just fine, others tell me to check the wiring to the alternator and to check for other wiring issues...
This has been going on for YEARS and the electrical system of my car has been beyond a headache. It gets worse as the days pass. I absolutely cannot drive at night anymore and when my engine kicked off for the first time and jerked my car it's time take this issue seriously.
So, WTF should I check and try and replace???
I do know that I am checking ALL wires tomorrow and looking on going to a bone yard to get a new ignition plug since the one I have was kind of ghetto rigged and I was planning on redoing the wiring for that anyway.
If nothing improves after that I am going try the voltage regulator... Or should I do that first?
Any other ideas?? Things I should check?? Try? I am trying to keep this as cheap as possible since I am a single mother.
Again, this has been an issue for YEARS and anything that I have found wrong and fixed, like severed ground wires or even the ignition wires when my car completely died has NOT fixed the problem.
