Bill560 Posted June 30, 2006 Share Posted June 30, 2006 My 95 Es factory amp is killing my battery if I let the car sit for more than 16 hours. What can I replace the amp with in terms of a swap from a different or same model dif year Lexus? Or is there a cheap way out to replace it these days?

dcfish Posted July 1, 2006 Share Posted July 1, 2006 how do you know? I don't beleive it is the amp that is draining your battery. Do further tests. Quote Link to comment Share on other sites More sharing options...

I checked for a draw and that is where it was coming from! I then brought the car to a car stereo/alarm shop (friend) and told him nothing except something was killing the battery when it sat and he came up with the same thing! He told me it wasnt the first Lexus to have this problem and come to his shop. I then unplugged the amp for a few days and left the car sitting and no problem!

SKperformance Posted July 2, 2006 Share Posted July 2, 2006 It may be a faulty trigger but not the amp. Anythign common shows up on this forum and i have never heard of this type of problem traced to the amp. Quote Link to comment Share on other sites More sharing options...

Anythign common shows up on this forum and i have never heard of this type of problem traced to the amp. A faulty trigger? Does the radio trigger the amp? I checked on ALDATA and it shows the amp also has a constant power! Just to rule things out, I pulled the dome lights, trunk light, glove box light and the battery still died! Oh and yes I replaced the battery. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 2, 2006 Share Posted July 2, 2006 I would change the battery cables grounds form the battery. As well as making sure the alternator is producing 14 volts at shut down otherwise they seem to kill the battery easy. Quote Link to comment Share on other sites More sharing options...
Bill560 Posted July 17, 2006 Author Share Posted July 17, 2006 UPDATE Ok here it is, I took the amp out and have NOT had a problem since. I found another Amp and installed that drove around for a few days (not continuosly) :whistles: and did NOT hve any problems. I then parked the car for three days and and still NO problem. I then returned to the shop and no draw was found. After all this it was the stupid little factory AMP! Thanks Quote Link to comment Share on other sites More sharing options...

Did you find out what it is in the amp that causes this ? Quote Link to comment Share on other sites More sharing options...
