The battery must be disconnected, the serpentine drive belt removed, the wiring disconnected from the alternator and finally the alternator unbolted from its mountings and removed.

This is not a DIY job if you do not know what you are doing and do not have the appropriate tools. Have it changed by a competent mechanic or auto electrical specialist.

SOURCE: 1997 Satrun SL 2 alternator failures

Miserable engineering.

My '95 SL2 purchased new, ate 6 (SIX) alternators, that fantastic "27 patents" automatic transmission, two sets of front disks and finally dropped a rod cap at 56,700 miles of very civilized driving.

I 'sold' it to my youngest son for $1 as a hobby when he got bored with his Jeeps or to donate it to a fund-raising bashing contest.

Now, the reason the alternators die -

They are buried in the engine compartment and get hardly any natural cooling there and, I don't know what kind of stupid engineers GM employs these days, but that alternator at 105 amps rating must deliver up to 1200 watts of 12 volt power an d it is too small to effectively dissipate the 1200 watts of sheer heat it produces while doing it.

If you have any appliance that absorbs 1200 watts (10 amps at 120 VAC), just check to see how much heat that is and even if spread over a larger area and bulk of the alternator, you think that would be a good environment for the semiconductors that are used to make the DC and regulate it.

It's a absolutely insane design and convinced me to never, EVER buy another anything from GM!

Sorry to vent but it still irks me after over 4 years of trouble-free Subaru ownership.
I wish you luck.

the ignition maybe bad are the car is not all the way in park also check the battery to make sure it has a good charge and it does not have a bad cell in it and the terminals are clean.

Could be a bad battery and alternator, the alternator should still be covered. But the battery will need to be replaced, and make sure there are no short in the electrical system.

It is possible that you got a defective alternator, but it sounds like you have another problem. Of course, you should check that you have +12V on the field connection of the alternator as well as the battery terminal. I think a more likely explanation is that you have a broken connection or a blown fuse in the engine fuse block. If all of the electrical systems in your car are dead, that is a good sign that the connection between the battery and the fuse block is broken. If you have no power on the power (battery) terminal of the alternator and you have power in the fuse block, then check the fusible link (maxifuse).

Get back to me if you do not find the problem, and I will attempt to help you further.

Most likely you have a voltage regulator on the alternator going bad. That is why one test was bad then one test was good. The voltage regulator is most likely integrated into the alternator. Replace the Alternator and that should resolve the problems.

Car not able to stay on.

If battery keep dying in few hours then check if there is something drawing battery while car is of. It could be something easy like broken switch on door which leaves lights on to faulty computer which doesn't turn off . Sometimes those things are almost impossible to find and chaperone is to disconnect battery when leaving car overnight. Just make sure there is not electrical short somewhere which may cause car fire. Also is good idea to park car in quiet place, tur it off and listen for anything running, like radiator fan, ac blower etc.

Daughter called me ..car wont start. checked battery at Autozone...it is good. someone stopped to help them and bang on startere and it starts up. Bad starter. Starter replaced. Next day daughter...

it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.

good luck

I don't know what is wrong with my car the belt just recently broke and we had to replace it but before we did that the battery died when we were driving and we killed the battery trying to get the car...

sounds like it may be a bad alternator. jump start the car and if it gets going disconnect the negative battery cable and if it dies you have a bad alternator. It may die as soon as you unplug the jump start cables.

Where is the Alternator located in a 1997 Lexus LS 400

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.

Won't start without jumping

Start the car with engine running remove the + battery cable. If engine continues to run alternator is good and battery is probably bad. If engine dies then alternator needs replaced.
