So the other week, i was driving and my car suddenly lost ALL POWER. I pulled to the side and popped the hood and i found out my negative terminal had completely fallen off. so i hooked it back up and it was all okay again.

Yesterday, my battery light came on and i figured it was the alternator. I did the "headlight test" where i rev the engine with the headlights on to see if they flicker or anything. They didnt. I did the negative terminal test where i turned on the car and pulled the negative terminal to see if the car continued to run or not. It kept running so it wasnt the alternator... right?

I brought it to autozone and they said that battery was okay and that i couldnt test the alternator unless the battery was charged. But i figured it' cant be the alternator because of the tests i did before. maybe a loose wire or a bad battery or something? I dont know.

Now my seat belt beeping indicator beeps before I even start the car. I dont know how to fix that either..

I called to get a quote for an alternator replacement just in case and its already 300$ for the part. Is there a cheaper way to do this? I did it on my 06 TL but i'm not sure if the 07 Type S is any different or not.

I just need help. any suggestions?

 

Get a battery tender and charge your battery before buying an alternator.

Check and tighten all cables.

 

So you believe it's the alternator as well right?

 

I believe you need to troubleshoot everything before just throwing parts at the problem as it could save you money




or just throw parts at the problem until it goes away.

 

Every other day i would need to jump my car due to the battery being dead. I brought my car to advanced auto to check my battery and they said it was good. I replaced it anyway and a year later Ive had no issues. I would check the battery 1st
