Ok, so I just got this DB1 and it had a side post battery in it. I was having a problem with the terminals not making good contact, so I replace the battery cables with the corect ones (but I left the extra ground, never can have to many!). After putting the correct battery in it, it was starting fine yesterday. This morring I jumped in it to go to work and when I turned the key, all the power went bye bye. The starter bearly bumped, all the of the lights on the dash went out, the seat belt would not retrack and the window will not go up. I can hear some sort of buzing noise coming from the passenger side under the dash even when the key is removed. I have checked all the fuse (under dash and under the hood). Any suggestion on where to start? Battery is good, cables are tight and I sanded the body to knock the paint off to ensure contact when I installed them, and the main fuse is good but I swapped it anyway for the one in my other car just for GP.
