The battery in my mother's 1992 LeSabre Limited went dead this
morning. When I hooked up the battery charger this evening,
having it set to 10 amps, the needle jumped to 60 amps and I observed a
buzzing sound. Upon opening the driver's door, the very loud
noise seemed to be coming from the fuse panel. When I opened and
lowered the fuse panel, the sound was coming from a black box above the
panel. It has a large blue unmarked decal on it and is stamped
with the following: 25601511 AJK

and a barcode label that reads: 3009174 AA EIA 528
91278. I cannot find my service manual and I have no idea what
this unit is. It is definitely the source of the buzzing.
My mom recalls that not even the interior lights would work when she got
into the car to start it and she noticed a low buzzing. When I
connect the charger, the lights are extremely dim. I also noticed
that the doors locked when I connected the charger the first time.



Any ideas of what the specific problem is or what that box is? I thought the ECM was located towards the passenger side.

Ok got brave and tried to start it. Everything went beserk.
The power antenna went up and the stereo started producing static, all
of the warning lights flashed on and off, the spedometer and fuel gauge
moved to several different positions and the clock flickered random
numbers. Then the whole works blew the 20A breaker in the
house. The charger was is rated at 50A for jumps. I took
the battery out as various different hidden components made buzzing
sounds while the charger was simply connected to the battery, including
some from the relay block. After attempting to start the car, the
box above the fuse panel ceased to buzz. After disconnecting the
charger from the battery, I could not make the headlights and park
lights turn off. Pressing the buttons on the doors simply made
them flash off and back on again. I've put the removed battery on
charge overnight and will try to start it again in the morning.
Fingers crossed it works, if that's not the problem, I'm lost.

 

Sounds like its time to bite the bullet and have it towed to the deaer.


Were there any code flashes before this happened?


Code reader rns about $25.00. Might be worth it.


In any case good luck[img]smileys/smiley16.gif[/img]

 

If the charger tried to supply over 60 amps, there must be a short somewhere. First guess is that the battery is shorted internally, which can happen if the grids break. But that would happen on your bench charge also. So look elsewhere. You might have triggered the security system. Any chance you hookedthechargerup backwards?

 

If you did hook the charger up backwards, you have likely damaged things, such as the ECU...

 

what options does the car have.


Anti theft? anti lock?
