Car will start fine for a week or 2 then sometimes my battery will be drained and won't start in the mornings. Battery has been tested and is fine. So I must have a drain somewhere. Whats the best method to use in order to find it??

 

disconnect the pos. lead on the battery. get a multimeter, set it to amps. put it in line with the + terminal and the battery cable (like an extension) . it will read how many amps the drain is. then start taking out fuses until the meter reads less, that's where your drain is.

 

Or just remove the fuse and probe the contacts with the ammeter. That'll be a lot easier than pulling a fuse and running around to the front of the car to check the meter at the battery terminals.

 

that should work too, i just have a meter with 10 ft leads and alligator clips, i hate bending myself up under the dash to probe all the contacts.

 

Don't have a multimeter/ammeter? A test light will work, and cheaply too. Disconnect either battery terminal and install the test light in series with the battery terminal. If the bulb lights, you have a draw. Pull fuses until light goes out. That will determine the circuit.
