If you tried a new battery and it still drained the new battery
get a multi meter and try to trouble shoot where the drain is coming from.




1.)Pull the positive cable off of the battery, w/ the key off. (Be careful not to ground the wrench!)


2.)Put a multi-meter in-line with the battery cable and the post you just removed it from. Set it to current (Amps).


3.)If it shows any reading, something is draining it (i.e.- the battery is probably good). Make sure all the doors, etc. are closed, so nothing could be causing a drain, such as the dome light.


4.)If the voltage meter does show a drain, then pull the fuses one by one, and see if any one of them makes a difference. If you pull one, and the meter goes to zero, the offending item is on that circuit. Get out the shop manual and look at the wiring diagrams to see what is on that circuit.


5.)If you pull one, and it drops significantly but not all the way to zero, then you may have more than one bad part and will need to repeat the following steps more than once, for multiple circuits.


6.)Check the electrical parts/equipment on the circuit, and look for anything obviously wrong with these, such as corrosion. If nothing visible, then it might be something internal to the parts. If there is a particular part that you suspect may be bad, try replacing it with a new one or known good one.


7.)After this, just to make sure that you really have found the problem, look at the multi-meter again. i.e.- you may have more than one bad part. If the meter shows zero, congratulations, you are done!


8.)If the meter still not read zero, after checking all of the fuses, it is something that is not on a fused circuit. Check the shop manual for everything that is not on a fused circuit, and and look for obvious problems or test by replacing with a known good part.
