99 Es300 Electrical Problem
Hello my name is Andy/Andrew (I go by both) but the reason i post here today is because i have been having electrical problems with my car since i bought it.(Used)
This car has a kill-switch in it. The car will drain the battery in a matter of days if i leave the kill-switch on while the car is off. Many people have looked at the car but they have said nothing is wrong with it. The alternator is working perfectly also. I just had it checked awhile ago..When the car is on, the car's electricity works fine...Until you turn on the a/c. When I turn on the a/c when the car is stopped, like at a stop light, the cars battery light comes on and the car cuts off the radio (if the radio is on). After I turn on the a/c and the battery light comes on at a stop, the car has a difficult time starting up the next time. On occasion the car wont even start unless I get a jump from someone (after the a/c is on). If i don't use the a/c the car will run perfectly fine.
Please help me understand and possibly find an answer to this prolonged problem. Thank you for all of your help and consideration.

make sure your battery terminals are clean and the cables are on tight. also if you have a volt meter test the alt and battery when it starts acting up and see if the alt is still charging. you could have a bad alt underload or bad battery

Tested battery and alt. Both my personal testing and autoparts both said they were fine. Terminals are clean and tightened. Car still had trouble starting today.

you have to check it underload and when your starting the car. try to duplicate the problem and then test it while its doing it. turn on the ac and check it and see what the reading is.
