If the voltage on the alternator and battery is 12.5v . is it supposed to be 13v n up?
Is somthin wrong with my alt. or batt.?
Cuz if the car is just in idle, all the lights go low and it takes long for the windows to go up or down.
All the power is good when the car running.
Any input would be greatly appreciated. Thanks

your battery voltage is good
a fully charged battery should be about 12.6
your 12.5 is good i wouldn't worry about it.
