I need some help!

Ok i own a 1999 Corvette. Well when i first got it, the interior lights (like the clock) were pulsing, and the headlights would dim whenever you put the blinker on or use the windows. So i went to autozone, and had them check the alternator and they said it was bad. So i put a $180 brandnew alternator on it. Well it was good for about a week, but now the lights are starting to do it again? Any help?

you may have a bad ground or a short in the wiring somewhere for the electrical???

The battery may be bad from the old alternator not charging it fully.

The pulsing is from the diodes going bad. In a rebuild the biggest expense is replacing the diodes so sometimes it isn't done. Either go for a remanufactured unit-or new next time. Get it retested,some garages will do it for free if you know one with a good tester (better than Autozone that is).

What do you mean new? It was a brand new alternator. Where are the diodes at? thanks
