Hey!My lights on my speedo pulse a bit when I am at a stop light.Is it my alternator?Is it the cold weather?

 

Use search. There couple threads about it.

If it flickers only on idle, usually it is an alternator's rectifier.
My dash is flickering almost since I own my car (2yrs+), I tested alternator and it's fine. 2 years already and it's Ok, but dash flickers

If its really bothering you, replace the alternator or just rectifier in it.

 

alternator symptoms for sure..

 

IT IS THE RECTIFIER. i know this cause same thing happend to me. all i did was replace the rectifier and no more flicker.

 

Actually the question regarding this.
I drive my car for a long time with flickering dash on idle.
Just a thought, do I lose power with alternator like mine?

 

its the same thing...the rectifier.

 

I know that it is rectifier. I'm asking - does my car lose any power due to bad rectifier?
