I suspect I have a slow battery drain - like the glove box light (which I removed). Any suggestions how to determine if there is something slowing draining the battery, and how to track it down. The battery looses charge after sitting a day or so, just enough so it turns over slow, or not at all on the second attempt. The alternator is putting out 13.5 volts consistently, even with load so I don't think it is the alternator.

Funny things happen to the ignition switches??

The standard way to check this stuff is to hook an ammeter inline with one of the battery cables and see how much current is being discharged from the battery. If you have a drain in excess of 30-35 milliamps then you will want to pull the fuses one at a time to see if it goes away. If you pull a fuse that causes it to go away then you will need to isolate whatever is on that circuit that is causing your drain. If you have pulled and replaced each and every fuse one at a time and still have not isolated it then you need to look into your non fused stuff like starters and alternators. Make sure that there are no loads on the system while you do these checks, like an open door or hood light or anything of that nature.

When it gets dark tonight, pull down the pass through to the trunk and check the light in there. Sometimes the switch gets turned when a box gets shoved against it.
