I have a 2005 century, last night the batt light came on going to work, when I turned the car off it wouldn't start. But the next morning it turned over and started bud died right away. It'll jump, but dies after removing the cables. I replaced the alt, and batt. As soon as the batt drains it dies. The batt light isn't on constantly. Also most of the time I get out and touch the driver door, it will shock me. I'm currently unemployed, any ideas? I did wire brush a couple grounds and reconnect. I'm really at a loss. I'm not much on the electrical system, but I think a positive wire is grounded somewhere. CAN U PLZ HELP!!
You may want to check the alternator/generator fuse in the engine compartment fuse box.
If this fuse is blown the alternator's voltage regulator will not get the battery voltage it needs and will result in the alternator not charging the battery.
Check the fuse map on the cover of your fuse box.
It looks like it's fuse 21, but check your fuse box cover to be sure.
Also, it looks like your Alternator B+ wire is connected to the Battery Positive wire at the starter solenoid and there's a 12 gauge fusible link in the Alternator B+ wire just before the connection to the starter solenoid.
.
You can use a multimeter to test if that fusible link has fried.
.
1. Disconnect the Negative wire from your battery's Negative post.
2. Set your multimeter in Ohms mode.
3. Hold the Red Probe of your multimeter on the B+ stud on the back of the alternator (where the big wire attaches)
4. Hold the Black Probe of the multimeter on the Battery Positive post.
5. If the multimeter reads about 0.5 Ohms then the Fusible Link is OK.
6. If the multimeter reads "infinite Ohms " (OL) the Fusible Link is Blown and you'll have to go to the Auto Parts Store and buy a new Alternator wire (Easy) or cut the Fusible Link out of the wire and install a new one (more difficult)

Also most of the time I get out and touch the driver door, it will shock me.
When you slide off your seat (which is usually synthetic material) to get out, you generate a static charge on your body. To avoid this, hold something metal before you move to let the charge escape.
Test your alternator, even the new one. (New does not equal known good). Check your drive belt and pulleys. If there's slack or binding bearings, that, too, would negatively affect recharging.
Another strong possibility: A parasitic draw, draining the battery It could be some module or sensor not turning off, remaining awake,or a circuit with a power/ground issue.
Should not be getting zapped touching your door. You've got a short somewhere which is killing your electrical system.

Go down and look at your starter. Sometimes those connections can get hot and short out to ground. The starter will still work but cause a drain. Also make sure your alternator was hooked up correctly. Measure with a meter between negative and other chassis points on your car. If you read voltage you have a short. Disconnect the alternator and test again. Then starter and test again. Make sure you have the positive cable off the battery whwn you disconnect anything for testing.
