Ever since I did the 6.0 swap when I go wot my battery light goes crazy, now I dont see any change in my voltage, it stay around 15, or a lil bove 14. Anyone know what could be causing this?

Check the female ends in the connecter going into the alternator, mine were over streched form prior owner checking plug with wrong size male test leads. It was't sending the charging signal back to the PCM hense the battery light on my truck. Just a thought?

i don't know if this works for our trucks but in the older style trucks you can start it up and while it is running, disconnect the battery and if it dies you know it is the alternator. the alternator should power the vehicle w/o the battery.
