I just bought at 2000 S 2000 and the previous owner told me that it had a very small electrical leak. It would drain the battery after several days of not driving. He suspected that it came from an aftermarket stereo installation. Being a new owner is there anybody that can recommend a way of detecting where this leak might occur?

 

Try testing for this
