go to auto zone to see if its the diodes..if it does then BINGO get the new rectifier assembly and replace and that will fix it...again same thing happened to mine 5 months ago...

 

my car do the same all the time(only cluster), i had her for more than a year now & everything seems fine

 

I have the same thing, my cluster blinks if the car is at idle.this weekend I put my multimeter on the battery while the car was off, then anoter time while the car was running and it measured around 13volts. So it seems my battery and alternator are fine.

Is there any truth to the "bad ground" theory?

 

^^^ its the diodes!!!!! my battery and alternator checked fine!!! you guys are making it harder than it is....

 

is there a DIY for the diode?

 

^^ what he said. my honda dealer checked alternator and battery and said they were OK. i made them extend my warranty because blinking cluster is definitely not OK.
