Question about 1992 Buick LeSabre

92 buick lesabre new battery, alt tested fine runs, then won't with lights

I had my battery replaced and the alternator tested and said it was fine, it will run for a day or so, then it won't start, clicks when I turn it over. I can jump it and it will start right up and run for a day if I don't use the lights but if the lights are on it dies. The Volt light stays on permanently, also a light that says INFL REST comes on. What does that mean. Any ideas of what I should do. Posts and cables have also been cleaned.

It sounds like there is a short or something...something is drawing power constintly and draining the battery. Something like this is usually hard to diagnose and requires a lot of electrical testing to determin where the power draw would be coming from in order to fix the problem. I would say u may need to have somone test your electrical connections and whatnot to find the source of the problem. Hope this helps any, good luck!

93 buick lesabre with newer battery test shows charging system normal will not turn over in morning. Something drawing down battery overnight. When jumped will start and run fine during the day.


First, verify that none of your lights are remaining on, especially the TRUNK LIGHT and the GLOVE COMPARTMENT LIGHT.
Second, after you have driven the car for several miles, turn the car off and let it sit for one to two hours. Feel the back of the alternator. If it is hot, REPLACE THE ALTERNATOR, and your problem will stop (bad rectifier diode).

Why do i lose voltage intermittently from the alternator when i step on the brake ?


what engine size?
the PCM runs the show, and its bad. or wires bad to it.
your car has PCM regulator.
no charge battery light.?

1: takes a good battery and battery cables and lugs cleaned.
2: test the altenator, odd how 4 of yours all tested good but you replaced it 4 times, get it tested if good, its good.
3: then check that the charge .battery lamp works. if the lamp works
that means the PCM thinks that charge system is bad.
if the wires from the rear of the alt, to the battery red and Gy wires
are good all the way to PCM then the PCM is bad.
the big wire on rear of ALT , on one car had a bad lug. #6 wire.
he replaced the ALT 6 times. all wasted effort.
inspect the wiring first. that is free, and is simple fix.
and if the ALT casing is not grounded, all bets off.
same with battery minus lug not good, on BOTH ENDS>
one guy had his battery lug moved to frame, (wrong)
and this never worked.

Replaced alt twice in two weeks


I had the same issue a month ago. i'm not a mechanic. i took it to the local garage, and they replaced the alternator. when we picked it up, hte light came back on. he said it was the control module and asked us to go the dealer. the dealer replaced the alternator with an OEM altenator and it has worked since. was the first replacement bad or is the OEM different. not sure...but it has worked since

My 1994 lesabre won't charge. It has a new alternator and the battery tested fine. Is it the PCM? or??


could be but i would check the terminals to the battery first. if it's the soft lead kind any crack at all small or large will not let current pass either way

On 92 honda civic the battery light stays on. Is


No your alternator is not longer working correctly. It could be as simple as a broken alternator drive belt. Open the hood an see if you see any naked pulleys. If the belt is in place then you most likely with have bad alternator. NAPA and Autozone have stores that can test your old alternator. Con comeone into removing it and have it tested. If it is bad get a REBUILT one. A new one will cost a small fortune!

My buicks battery has just died. When I jumped it it goes to turn over for a second with a click and then dies down, but all the lights come on. How do I know if its the starter alternator or battery


if the lights are bright and you hear a clicking and your heat blows good, the head lights are still real bright after trying to start a few time replace the starter (you can try to hit the starter with a hammer otr somthing heavy a few times and then try to start if it sounds better or starts replace the starter) if the battery goes dead try to jumpit if it starts then dies after a few min its the alt if it starts runs good and you let it run for about half hour shut it off and it wont restart rite away its the battery.

1988 Buick Lesabre drained battery


Sounds like you have a bad alternator. but first , check the battery connection o the positive side where the cables overlap eachother. they like to corrode in between the two cables and do just what your saying. but it really sounds like you need an alternator. have someone check the red wire on the back of the alternator and see if there is power there al the time- should be. if so replace the alternator, i have had many new or not vary old one fail. - good luck
