voltage question 02 z06
I've got an '02 z06 with 41k. If I step on the brake or put the turn signal on, etc, the voltage displayed on the DIC will quickly drop from ~14.5v to ~13.5v. The headlights/dashlights will dim for a second, then go back to normal. I think my battery is the original; would a bad battery cause this kind of problem, or would it be more of a alternator or ground issue? I'd appreciate any suggestions.
Thanks

I think they all do that to some extent, load on system and alt takes second to keep up I would think. someone with greater knowledge will comment

If your battery is the original from '02, then you're due for a new one. If you want to make check with your local auto parts store or, your mechanic and see if they have a battery load tester and check it out. All cars will experience a little quick drop off in voltage when you add more load to the system but, if you possibly have a 7 year old battery, I'd start with that. Good luck.
