SOUND LIKE ALTERNATOR PROBLEMS CHECK ALTERNATOR DRIVE BELT.CHECK BATTERY VOLTAGE WHILE CAR RUNNING VOLTS SHOULD BE 13.5 TO 14.5 VOLTS. IF NOT ALTERNATOR FAULTY.ALSO CHECK ALL BATTERY CABLE CONNECTION MAKE SURE TIGHT. AND TURN OFF RADIO BEFORE DISCONNECTING NEGATIVE BATTERY TO KEEP FROM LOSING PLAYING CODE.

For the battery light, test the alternator. If you have a voltmeter, check voltage at the battery with engine running. Voltage should be at least 14 volts. If you don't have a voltmeter, take the alternator off and take it to the parts store for testing.

for the brake light--may be caused by the alternator problem, but at least check the brake fluid reservoir. If it's low, refill and check the car for leaks at the wheels or below the reservoir/master cylinder.

Please let me know if you have any questions.

I was driving my 1999 hyundai elantra when my battery light and parking brake light came on at the same time. what does this mean? my P-brake isnt on either. but when i do put it on the dash signal gets...


If the battery light is on, your charging system is not working. This may have also caused the brake light to come one. Recommend you replace the alternator and see if that doesn't extinguish both lights. If not, please get back to me.

Have the battery & charging system checked out. Then, based on what you find out, Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

The brake sensor switch is located on the brake pedal. If fuses and bulbs are ok it should be the switch.

Hyundai 2001 elantra brake light weirdness


Hi joe its going to be that socket that has poor contact. It will more than likley need a the socket but try this first. unhook the battery, just so you dont blow the fuse. then remove the bulb look in the socket theres going to be 2 copper looking metal contacts bend them up alittle. this will take away the poor contact if thay are not cracked.If they are cracked you will have to get a socket.

I have a hyundai elantra 2001.. the brake light and the battery light both turn on.. what could be the problem...


Your alternator is probably not charging at full capacity. The brake light is next in sequence with the battery light, and will glow dimly. (Set your parking brake, and it will glow brighter.) I replaced the alternator, and cleared up the problem.
