Well Jennifer there is a quick way to do this start the engine lift the hood and remove the positive battery cable if the engine shut's off your altenators regulator is bad. Please note that is how I have always checked them. some mechanics believe that there is a potential for a battery to explode by doing this, however i never had this happen in 25 years of being a mechanic. you should still use caution when working on a vehicle . if the vehicle doesn't shut off then your battery is probabl;y no good. another altenative is take the vehicle to an auto parts store like Oreilly's and they will test the battery and altenator for you this is free of charge. please rate this thanks

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

the starter is located in the valley under the intake manifold. you must remove the intake to access the starter. its a pretty involved job. when reassembling take your time and make sure that every wire is plugged in and every vacum line is connected.
