My battery keeps dying. I bought a new battery 2 weeks ago with a new alternator. But it still dies out in a week. I've checked to see if there's something that drains it while off but didn't find anything. What could be the problem?

 

Get a cheap digital multimeter and check the DC voltage between the battery terminals with the engine running. You should see between about 13.8V and 14.4V.

If you see 12.65V or less with the engine running, then your alternator is not charging.

 

How did you test for a drain, did you do a proper parasitic drain test?

When you say the batt. drains in a week, do you mean when just parked or even if you run the car? 94

 

I have tested and it reads at 14.15V.

 

To test the drain I used a multimeter and check various wires. I drive it daily and I goes out in about a week. since the last time it happened surprisingly it's been 2 1/2 weeks.

 

Either the alt. or voltage reg. is bad, have the system tested at a batt./alt. shop, most will do it for free. 94
