I have a 2005 civic reverb.It only has 115,000kms on it.I have noticed that the headlights and all my interior lights including dashlights are flickering really fast.I went to partsource and they checked my battery and altenator both came up running fine.I cleaned my battery posts also and still they all pulsate.Does anybody have any ideas I am can't figure this out.Thanks

 

Check that the "I" wire to the alternator gets battery voltage when the key is on. On older models anyway, that wire was yellow with a black stripe. Alternator may be going bad anyway-- though it still makes some voltage, it varies.

 

Ok I will check that out,thanks
