I have power problems. =(

I recently added a hard drive to my setup, and it seems to have uncovered some larger power issues i am having.

Long story short, i realized last night that even with its own power adapter, my hard drive doesn't spin up when i have headlights/AC turned on. with these on, i get voltage drops to 11.5 up front, 12.5 at the cap. During the day i am usually fine, getting nothing below 13.3 when pushing my substage hard (if ac is off). I get no dimming whatsoever, which confuses me somewhat...

So the question is, how can i fix this? Big 3? power directly from cap or battery for the hdd power adapter? vehicle is in my sig, i believe its a 65a alternator.

thanks

New high powered alternator would help a lot. Maybe get a 12v+ power regulator that puts out enough amps for just the HD alone.

get rid of the cap and install a sealed battery and you'll be fine //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
