After 2 to 3 days my battery is dead (~2.5 vDC). After jumping it, the alternator charges the battery fine (~14 vDC). I connected a meter to the battery and discovered ~0.8a current draw on the battery, but then decays to nothing. After I touch the cable back to the battery, the current draw returns.
Sunroof switch operate intermittently.
Trunk light does not work...no voltage to terminals and no blown fuses.

Been talked about a bunch

I'm still suffering with mine . I'm waiting for my new alternator to arrive soon. I have a new Optima red top battery. I wasn't able to find a problem from the fuse box. I'm real stumped with this one. I will post when I do figure it out.

Use a VOM in the current setting (amps), remove each fuse in sequence and measure the current flow.

My mechanic did some testing like that and wasn't able to find a problem. I'm going to remove my battery and charge it and let it sit for a couple of days and see if it's holding a charge. My new alternator is on its way, but got held up at customs, so looks like I should receive it this coming Tuesday.
