Turn the key, have no power at all. I can jumpstart it if I leave it hooked up long enough, but as soon as you cut the car off, it loses all power again. When it is running, if you hit the brakes, all the lights in the car dim. I put a brand new alternator on it today, as it failed an alternator test at O' Reilly's. I've checked my battery connections and fuses. My battery is good. I pulled it out of the car and tested it with a multi-meter, and it read 13.7v.

Anyone have any ideas? If you need more info, let me know!

Thank you,

Tommy
