1998 crysler sebring battery blew up so I bought alternator and brand new battery put them on and my abs light stays on and battery light stays on what could be wsdong

First check your battery. If it is not fully charged then you need to give it a full charge and then have it checked to see if it is good. If the battery is bad that is your problem. If it fully charges and tests good then it is most likely your alternator. If that checks out then I would check the starter......unless it is turning over ok.

Take the car to a local Autozone and have the Alternator tested, it is free. Also when the "Battery" light comes on it doesn't mean there is a problem with the battery persay it means the battery is not getting charged up while you drive.

Auto Zone does not test the alternator under full load so the test result could be borderline.
start the car and turn everything on. If the voltage drops lower than 14.2
replace the alternator.
also the battery could be being drained overnight. to check use a test light by removing a battery terminal and connecting light between battery and cable with car off.
if it lights start be removing fuses.
when the light goes off the problem is with this circuit.
lastly if the light stays on take the wires off the alternator.
if the light goes out replace alternator.

alternator voltage regulator failing have alternator checked out at any auto parts stores.they can check alternator out put with battery in car while engine idling.most time alternator failing will cause headlights dim and vechile stall out.

Dead battery.....bad alternater.....bad fan belt.....bad starter

If you lights and radio work, it probally isn't the battery or alternater

Here's a thought...I had my ABS light staying on and all I did was add brake fluid...maybe this can be helpful to you?

If the battery light is on, the alternator is not ok if the battery is new.

Good luck to you.

ABS is Advanced Brake Systems, but that light should flash once when the car is turned on to signal it works.
If you turn the key in the ignition forward, like you are going to turn it on, but not far enough to turn the engine over, that light should be on at a constant. with it turning itself off upon starting.
If you have a no start issue, it would have the same effect. But if it is a no start, it's not going to be a dead battery, the battery puts out enough charge to turn the engine over (on), and the alternator runs everything.
Alternators run off the belt(s) on the engine and need exact tension, in order to produce the proper amount of power.

check alternator and battery. your abs light will flash . if your alternator . not charging. it needs 12 volts to operate. check your belt also.

head light relay in fuse box under hood by battery box lid shows diagram location this would be a great place to start!!!good luck
