2001 zetec electrical

So I have had a small electrical snafu for almost 3 years now. My interior and exterior lights flicker, not to an extremely noticcable point but when it started I had my alternator replaced and that didnt help. Its not that bad bcuz as I mentioned I have been living with it for 3 years. I had my VIN checked to see if the car has ever had the battery cable recall done and it hasnt. Could this cause that problem? Bad grounds? Bad pigtail? Anbody ever experience this before? I had my voltage tested and it does fluctuate a little.

Get your self a multimeter from Harbor Freight less than $10.00 sometimes even less than $5.00

Go to YouTube and type in search: Alternator battery multimeter there you will find a whole multitude of videos of varying quality
You need to learn the voltage of your battery when the car is off
When the car is running
When car is running and headlights and heater are on
THEN
Switch the multimeter to the AC Volts scale and measure when the car is on across the battery you should see zero
If you see any volts then try the same thing with another car to rule out multimeter weird problems

Yes you can turn the cluster into a voltmeter I will let others tell you how to do that but that trick will not be able to measure AC Volts on the battery [ In high school I made a DC voltmeter, crude? of course! but that lasted till i went to electronic technician school]


AC Volts across battery = Alternator diodes are shot

BATTERY CABLES:
Any burned insulation on the wires leading up to the battery clamps?
Battery clamps must be CLEAN
Tug as hard as you can sideways on the battery clamps, they must NOT move! If they do and the clamping nut is tight there is a fix for that

Okay, yea I figured I should get one so I could keep an eye on the voltage myself. About the cables, I do have some exposed copper wires towards the ends of both batter cables. The negative cable has some loose strands even, should I get this fixed

if you hadn't had a recall relating to an electrical issue done why are you wasting forum space about an electrical issue, take it to the dealer and get the recall done

Hmmm sort of hard to tell just from a description-- need pictures
but the important thing to note is melted or burned insulation!
Them electrons are invisible! have to make them appear! via a multimeter!

I doubt after 12 years there is a valid recall on those cables

Recalls are valid for life of car as long as the vehicle has not be declared a total loss by an insurance company or has been issued a salvage title
