Flickering lights

Recommended Posts

My head lights, dash lights, instrument cluster lights all flicker at idle and my voltage read out only hits 14.5 now instead of 14.8.  

it only does this at idle, no amp in the car so no stereo playing while it’s happening. 
 

voltage gauge I dash goes up and down also with the flickering. 
 

is the alternator going bad?? 
 

it didn’t do this for the first 5 months or so I had it.

 

370 elite in an 05 tahoe and it has 1 wire that goes to acc power.

Loose ground? Loose belt? 

Grounds are good, I might try a new belt and see if that helps, at this point I’m lost.

Spray some belt dressing on the belt and see if that helps before you get a new one. If it helps then get one 

Wondering why though it’s only out putting 14.5 instead of 14.8.  I can also see if I rev it up then let the Rpms drop back to idle I can see a voltage drop into the 13s for a second.

Highly doubt the belt has anything to do with it, if your "charged", or, over battery rest, the alt is really not even doing anything, charge wise, hense, belt slip wouldnt be a concern. Id be a bit more worried why the voltage fluctuates when you rev it. Again, i highly doubt your pulling much of a amperage load, to make the belt "slip". Have you spoke to mechman? Those elites are pretty damn bomb proof from what ive seen though.
