You may have to remove the power steering pump in order to get your hands down in the passenger side of the engine to remove it.
when reinstalling pump be careful not to let any power steering fluid drip down into alternator. That could cause a premature failure of the alternator.
If you can,drive to Autozone,they can scan your Lexus and test your battery and alternator and tell you why that light is on,it's free and only takes a few minutes.
The main purpose on an alternator is to recharge current back to the battery. One of the most common problems with the Lexus LS400 and SC400 is that power steering pump seal leak. Right below the power steering pump is the alternator. The power steering fluid will drip down and cause many electrical problems for the alternator. Therefore, its very common to have the alternator go bad along with the power steering pump, just be sure to check.
The voltage regulator for the alternator is located inside the rear housing of the alternator. It can only be accessed by removing the alternator and dismantling it. If the regulator is faulty it is repair by replacement usually by swapping for an exchange unit from an auto electrician. If the alternator is not charging it may just be a case of the brushes inside the alternator being worn out and requiring replacement.It will still be required to remove and dismantle to carry out their replacement.
I would inspect your wires at the starter. If you live up north then corrosion is bad, clean all wires going to starter. then clean wires to back of alternator. I seriously doubt that alternator is the problem, but if you remove it you can have it tested for free at most parts stores.
If the car ran and got you home after a jump start I doubt the alternator is bad. Check your battery. And remember never ever disconnect the battery cable with the engine running.
