If your having a problem with a battery going dead, either the battery needs replacing, the battery isn't getting a good charge, or there is a short. Hook up a volt/ohm meter to check the voltage when it's running. Should be 13v.-15v., if I remember right. Also if ya have alot of lights and or accessories, the charging system may not be able to keep up. You can check for a short simply by removing the negative battery cable and hooking a test light between it and the battery post. If it lights, there's a short. If you do find a short simply remove 1 fuse at a time till the light goes out. Then you have to find what is on that circut that's causing the problem. This all applies to just about any vehicle. Good Lock.
