Been having an intermittent Check charging system and battery indicator light flashing with it. New Alternator this week and battery less than year old. All components appear to be working fine. Any ideas would be helpful. Thank you

Using a Volt Meter read the voltage at the battery with the key out then read the voltage at idle then read it at about 1500 to 2000 RPM's
Post those 3 voltage readings

ok now the truck wont start. I actually sat in the truck watching the battery gauge drop. its like the alternator is not charging it. so I am unable to post the 3 readings right now.

Double check all wirings you connected with the new alternator for looseness and corrosion
