I just bought a 93 Camry V6 SLE and the seller told me the battery drains overnight. When I looked over the car I noticed that the driving night lights were on while there is no key in the ignition. Once you turn the key and start it up the light go out. I figured this was the drain that was killing the battery so I have been disconnecting it when I'm done driving. I just bought it and have not had any time to really get under the hood. Does anybody have any suggestions? I should mention that the seller told me she was having trouble with the alarm system.
