Maybe a short allowing the current to drain to the body?

If it’s the former, it’s not a problem.
If your turn signals or other lights were the problem you would be blowing fuses.

My car will drain will driving, the volt meter just slowly drops. If you flip on the blinkers it will drop a volt untill it is flipped back off. I know this isnt the problem, but its just an example to show that my car isn't charging or holding a charge like it should.

Have you had the alt tested? Just because its new, doesnt mean it cant be bad.

Re: All Alts Work Good Over 150 MPH
i just checked my alt again yesterday and found out that i had forgot 2 run a hot wire to the alt. duhhh. after i ran that wire it worked like a champ. 12v with the car off and about 15v when its running which is supposedly normal. thanks for the replies guys

Re: All Alts Work Good Over 150 MPH
I have an 87 Iroc and have had the same problem for years now....I think the only way i may solve this is to buy a 140 amp alternator. I hear FAST makes one for your vehicle...I have a brand new Optima battery and good grounds...So i am also confused myself..SOrry i couldnt be of more help.
