Nissan Altima 2004 battery and brake light went on and later the acceleration was slow
I started my car today and both the brake light and battery light was on.... i drove for about
20 mins and suddenly the car slowed down ...I turned off the engine several times and it
worked fine for 10 mins or so and again while i stopped in a light it started to slow down
again and I again tried to restart the car but didn't work. What should be the problem be?
Battery + Brake Light is Nissan's warning for the alternator. Easy way to test is once the car is running, probe the battery with your voltmeter and if it is under 14V, it's time to replace the alternator.
Do you think it is ok to drive till my mechanic if it drives ok in the evening? Can you give me the estimation on cost to replace alternator. thank you!
It might as long as the battery has enough power to start the car a few more times. Put your jumper cables in the car just in case. Avg. cost to replace the alternator with labor is $400. Not sure what your mechanic will charge, make sure they check the condition of the battery, and charge/replace if necessary.
I agree with Tom. Also, a good auto-parts store will test your alternator for you for free. Also, how old is your battery? Is it original to the car?
