I think my alternator may be dead.

    I think my alternator may be dead.

    Last night, my car wouldn't start. No lights, no radio, nothing. It started up the first time when I got a jump, but then when I turned on my headlights and pushed the brake pedal to shift out of park, the dash lights dimmed a whole lot. The same thing happened when I put down my driver's side window.

    On my way home, the car was very weak when I wasn't pressing the gas pedal. It almost died at a few stoplights, so I started keeping it in Neutral and giving a little gas while I was stopped. When I got home, and turned it off in the garage, I tried to turn it on again just to see what it would do. Absolutely no power.

    So I took my battery back to the store, where the Midtronics Battery Disgnostic System concluded I have a good battery, cranking out 736 CCAs at 12.71 Volts.

    So, somehow the battery is definitely not getting charged. And, while driving, the electrical system is not getting as much power as it needs.

    If it's helpful, I replaced the ignition switch assembly last week. As of today (Saturday morning) I am working in the garage to remove the alternator so it can be bench tested at the auto parts store.


    Thanks in advance,

    Ben <><

      Check your grounds,around the battery and check wires going to the alternator.

        I took the alternator out and had it bench tested today. It is good.

        Thanks, that's my next step. As soon as I hit Submit Reply I'm headed back out to the garage to try again.

            He said his battery was good already.

                I FIXED IT! After racking my brain for hours and hours and hours about the complexities of my car's electrical system, I decided to look at simple things like wires. And lo and behold, the main ground wire that runs from the battery to the engine block was detached! The screw that attaches it had come loose, I guess, and fallen out.

                I learned a lesson today: When troubleshooting, always start with the simple stuff!

                      On my accord I had a similar problem it was the one to the battery to near the fender it broke off and everyone said it was worthless so i replaced alternator and it helped but when i did that ground worked great.
