Flickering dash lights
Hi all my 1998 chims lights flicker mainly the dash dial lights and the dipped lights but not to the same extent as the dash ones. Any one got any easy ideas? I was thinking a bad earth??

Cheers Scott

does the flicker change when you rev the engine?

Dodgy alternator?

Might be worth checking out your 100-AMP fuse - mine did similar when it had snapped

+2 get the output checked for erratic voltage(fluctuating readings)normally cured with a new alt or alt regulator assy.

it flickers when the car is on the move at higher revs which made me think it may not be the alt??

got same problem on mine,
having alternator checked on thurs and while its in , changing 100 amp fuse as well.
will let you know how i get on.

help....
100 amp fuse changed
alternator given clean bill of health
lights still flickering ??????

was the alternator checked with a scope or multimeter/volt meter?was you present when it was tested?

[joncon]

checked with multimeter.
they did it across battery terminals !
dont know if thats the right way or not ?

That wont tell you if it as a fluctuating output(to slow to react to rapid voltage variations)i had the same problem as yours,mine showed no problem when used with a general purpose meter(infact ithad a good output,but not stable)it may be worth getting your unit either checked with a scope(on the car)or(off the car)a test bed for alternators(most rotating automotive reconditioners have this equipment inhouse)dont presume because its say banging out 14v under load that its all hunky dory

i will try to get that done asap...
garage were very friendly and didnt charge....
