there are a few diodes in the electrical system that have been blown.  Some are in the dash and some are in the different control modules in the car.  Your insurance should pay for this problem.

Not too bad. Not much room, just enough to drop the starter. It is probably easier to go up through exhaust if you can get your exhaust shield off the manifold .

Battery light on 96 lexus ls400 replace battery and alternator


Did you check fuse's ? there has to be B+ voltage to the alternator for it to work . Four wires at the Alternator ? If you want to try an fix this yourself , which I don't think you should if you don't know automotive electrical systems . Go to youtube an check out some videos on charging system testing an on basic electrical trouble shooting . Then go to www.bbbind.com/ for wiring diagrams of the charging circuit .

Where is the alternator located on a 1991 ls 400


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.awcforever.gif
