Okay, let me start by saying I am an indiot.
I drained my battery while doing some work on my SC400. I used a battery from antoher car to start the SC and then planned to switch the battterys so teh alt could charge the dead battery.
When I put the other car's battery in I hooked up the terminals backward (+ to black, - to red), the car was not running or even turned on.
I switched it back after about 2 seconds. Car started fine, then I put the dead battery back in, let it run for about 1 hour.
THen I test drove it, every thing seemed fine until I turned on the headlights. Driving, turned on headlights and the car went dead, everything: engine, dash lights, windows, everything.
If I jump start it, it will rubb until the cables are removed then it dies immediately.
What did I do?
Any ideas on what the probelm is?
I am getting the battery checked today, but it seems like something else is wrong.

Thanks,
Adam
