Is is my battery or alternator?
I have a 1998 honda accord ex 4 cylinder. My starter jus went out and was fixed. Autozone lost my battery i took in to b recharged and replaced it wit a "new battery" they got from the back. I've drove my car fer less than 48 hrs and now my car won't start. I didn't leave any lights on n the night before i had to push down the automated locks by hand. Someone said its my alternator, but i haven't had any problems wit it before. No lights were left on or doors open. Not even my stereo or my headlights were left on. Could it really be my alternator or did Autozone give me a bad battery?
First you have to get the dead battery charged. Then, using a voltmeter, start the car and measure the voltage with the engine running. It should be at least 13.5 volts. Leave the meter connected while you turn on the blower motor, headlights, rear window defogger, and wiper. Increase idle speed to about 2,000 RPM. Voltage should never drop below 13.5 volts. If it does, the alternator is bad. If it passes that test, then you have a parasitic battery drain. Read this post on how to find out what's drawing power when the engine is off
Take it back for a better battery, they lost the original
- Which car battery is better? EverStart Maxx Lead or Duralast Gold/Battery? Facts: I drive a 2007 Honda SE, 4 cylinder. Been using a Kirkland (costco battery; group size 51r) for about 5 years. Looking for a battery in case this one dies.
- Bought a 1985 Honda inspector kid told me it needed new battery but started with jump got new battery and it was dead next day? Pretty sure its the alternator just wanted some second opinions also I got the bike for 600 dollars you guys think thats a good deal
- Honda Civic Alternator stuck? I have a 2000 Honda Civic and I've loosened all the bolts I need to to remove the alternator belt, but the alternator itself won't move. Any tips on how to break it free so I can get that belt off?
- Car problems- is it battery or alternator or both? Car does not have enough juice to crank. Everything turns on but only clicking noise. I get a jump and it is fine for a few days. Yesterday radio starts turning off and on. Today the air conditioner (on full blast) increases power when I accelerate. Notes: 2003 Honda Civic 4 door LX 5 speed manual trans 1.7 L
