So I replace my alternator and battery. Went to go start my car this morning. It won't start. Had to jump start my car. It start right up but when I go to drive for 10 mile my battery light come on and the car shut off. Now I'm on the side street with no power at all. :/

Sounds like a bad alternator. Have it tested. I had a friend of mine that bought a "new" alternator, it didn't work so she end up having to take it back and exchange it, then everything worked fine

Thanks dude for the quick response. I will do that. Club Lexus is the best.

While you're at it, check your fuses as well

Measure the voltage when the engine is running. That is the best test. Should be close to 14V.

Could be a multitude of things. Alternator, battery, or starter. But as this happened to me the other day. Also could be this. The negative wiring to the battery. If they're deteriorated and getting really old, the car will eventually not start. I replaced the wiring (well my mechanic did) and it's been great ever since. But I had that problem. Car wouldn't even start. I was STRESSED. But I hope your problem is resolved buddy. Good luck and GODBLESS!
