Hi all,

Got a weird and annoying problem with my 2000 focus zetec.

Basically all the lights flicker on it, headlights, rear lights, dash lights every light seems to flicker at exactly the same time, which makes driving at night
quite dangerous.

Also after it's been doing this for a minute or 2 all the warning
lights come on the dash, speedo needle shoots round to 140mph, and odometer reads just lines.

Has anyone had this problem on there focus or know what's wrong, as it's a little worrying when my missus and our little one are in the car.

Any help is much appreciated as always

Cheers

Baz

 

Just to add the car seems to drive perfectly fine, no loss of power or anything,

Any help is greatly appreciated

my focus has had an earthing kit fitted to stop this

 

if everything is doing it, then i'd make a guess at an earth problem,
and as it is all doing it at the same time, possibly the negative battery terminal, loose/ dirty/poor connection??

seems an odd problem for sure!

 

Flickering in time with engine RPM could mean alternator is on its way out...

 

not that odd the original earths from batt to body and engine to body and engine to batt are rubish new conecting wires are needed like an earthing kit

 

No its not in time with the rpm's mate, just completely in there own time.

 

Battery/earth connections fella,there's a big block by the battery.check that theres no poor connections,corrosion,pure rust and so on.

 

Nice one mate I'll check all those bits in the morning, failing that any more suggestions

 

ok i had a mechanic check battery, terminals, altenator, all fine by him, so we're now stumped by the problem,

has anyone had this on there car and can tell me how to fix it, or whats wrong,

many thanks

Mate i have got exact same problem with my st170 all lights seem to flicker every so often.i have yet to check my earths.

 

if you find the solution before i do mate please let me know, its bugginh the shit out of me, lol

 

The smart charge will make the lights flicker slightly every now and then, normally when it's ticking over, you will see it flick very slightly 4-5 times. On the ST170, if the dash lights flicker, turn the brightness down slightly, that will stop it.

But the OP seems to be having more serious flickering so it must be something else!

 

Cheers rich mate you seem to be very knowledgeable with these cars.
Just bought mine from the inlaws and trying to iron out a few small stupid issues.

 

the early focus's had bad earth issues with the lights,
theres an earth connection behind a headlight(n/s i think)
the wires look intact but corrode in the terminal, cut the terminal off
and fit new 1, this usualy solves the earth prob,
tbh i dont remember it causing flickering but if its got a dodgy connection it could so worth a try anyhow
