Is my alternator going

[Billy177]

this is in my other x when i furst start the car in the morning before school it is at a good 14 volts. then when it warms up it will drop down to 13.4-5 and with all my lights on at idle it drops down to around 12.4

I would probably say it's on its way out. Your alternator should maintain about a constant 13.5vdc with everything on at an idle regardless of the temp.. That's all lights including high beams, A/C and fan on high. If you have rear fan in the console, that one on also.
