  • My battery is 2 yrs old. The car hadnt been driven in 3 weeks, everytime I come back to the car, the battery would be drained. Where do I start or how to do some basic diagnosis to detect the leak?
  • I wondered if the alternator is bad - but then after driving the car for 10 minutes - it fire up instantaneously
  • Is there a common electrical part that m ight go bad on the IS300? :confused:

Probably just time to replace the battery, get it checked at your favorite local auto parts store. Eventually they won't hold a charge.

Get an AVR test. It will determine, if you have a parasitic drain, or as stated no cranking amps to draw from.

Base line is about 175 to 200 CA (cranking amps) to start the vehicle. If your AVR test shows less or about this number. Go buy a battery.

Take off the negative terminal of the battery and bridge the terminal and the battery with a test light, the test light should light dim if everything is normal. If it lights bright then you have a drain. If you do have a drain have a friend pull the fuses one at a time until you pull the fuse that makes the light light back dim. That is the circuit that the drain is contained in. Get a schematic for that circuit and have fun!!!!!!!!
