Question about Lexus Cars & Trucks
MY LEXUS HAS A NEW BATTERY MECHANIC SAID IT WAS NOT THE ALNATANATOR BUT STILL IN LOSES CHARGE
Usually if if your alternator is good, once you had the engine running, disconnect the battery. If the car keeps on running then the alternator is good. You may also need to use a voltmeter to measure the voltages before and after starting the car. The voltage should increase once the engine is running. The alternator may be weak or your are draining power either through a gadget installed in a car or bad wiring that you may need to inspect your wiring.

Did you ask the mechanic to change the alternator,or did you tell him to fix it? I would spell it out to the customer myself(not the service writer) that I would prefer to do the diagnosis,but if they didn't want to pay it,then there are no guarantees,and document this on the back of the repair ticket(saved me MANY future arguements!).If you told the mechanic to fix it,then take it back and say "Try again!".If you said "Replace the alternator" then that's what will be done.If you have no change after replacing the alternator,then you have to figure out what's not making it charge.Verify the large cable to the battery is good with a test light.The smaller connector requires a wiring diagram to diagnose,however.
