Use a digital multimeter and check charging system. Any applicable trouble codes?

Just to add, you should be able to check mil codes, yourself. You turn key just till the dash lites come on, no further, cycle the key on--off, on--off, on. Then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes. Let us know.

I never got no flash, started the car up and the light came on again and after a lil bit of running, the radio starts to cut out and everything. Charging system is new, as of this mornin, alternator is putting out 11v. Something is preventing it from its full potential it seems . Battery is a few days old

Do you have a code reader? it connects to your datalink connector. Some of the national brand autostores will check codes for free. I checked two different databases, they both gave the procedure to check mil codes. Could be problem with instrument cluster--wiring circuit--computer. I hate to see you throw parts at it. That 11 volts is no good, should be 13--15 volts for the charging system. The pcm uses input from battery temp sensor, I cant say that sensor is faulty?
