Hello gentleman of antiquity! have a 2000 Lexus RX300, the battery is good (6 months old), no cel lights on and earlier I went to start the car I got nothing, no click, just silence, car's on a flat surface in "park", it's around 40 degrees. I checked terminal connections and all's well. I put the charger on it and I'm waiting to see if that at least allows me to start the car. If so, I'm guessing something's draining the battery after the car's shut off, but I can't figure out what. Any ideas would be appreciated, thanks so much! I have to say, I bought this car back in 2006 and I can afford to buy a newer car, but I love this car and its faithful service, lol, I can't seem to part with it!
