Battery light on dash came on having problems with electric
The battery light started coming on a few days ago. when i rev the engine the light would go out. this morning i could not get my turn signal to go off. when i turned the car off it would not restart. waited a few minutes it started but i had no lights of any kind . i continued driving to try to get home and the lights came back on. could this be an alternator problem?

if the cables were put on wrong yes..since it sounds like you are not mechanically proficient, go to a shop that specializes in auto electrical..they should be able to fix fairly inexpensively(cheaper than the dealer)..
I would have a battery load test done to check for a failed battery cell bridge or a dead cell. Lights will come on at low battery voltage but there is not always enough current to do any thing else. Check alternator drive belt for condition and tension. Have a condition test done on the alternator to see if it is charging correctly as it may have failed and the battery ran down trying to run everything electrical.
Besides the obvious: checking your alternator/charging system. If the check engine light is not on, or it comes on, and after awhile it comes off, then a couple of hours or days later it comes on again it might the crankshaft sensor. It happened to me, and it was a pain in the neck to diagnose as the check engine light had turned off and the computer wouldn't read any codes to diagnose the problem. My mechanic was trained by Mopar/Jeep, so he immediately knew what was happening.
If it is a dead or shorted battery, when the RPM's are up the vehicle will run, and you might notice a loss on power. Once the engine goes to idle and the RPM's come down the engine will die, as there is not sufficient electrical power generated by the alternator to supply the engine. A bad alternator will cause battery problems.
You have all the symptoms of a low voltage condition in the battery, Kragen and other parts stores like it will test your battery and charging system (alternator) for free, but it is pretty safe to say the battery is toast. Don't reject this solution without the test being done, I think you will find I am right, low battery voltage can cause trouble codes to be set and low fuel pressure to name a few..
