Check charging system warning

[Bedrck47]

To me low rpms are 500-1000 high to me is 1500-2500

So based on your other post do I take that to mean that the battery doesn't charge between 1000 and 1500 RPM's 0r over 2500 RPM's

Its not charging when its idling

Its not charging when its idling

FOR YOUR INFORMATION
Pic 1 was taken with the engine off key on doors closed
Pic 2 was taken with the engine at idle 13.8 volts
pic 3 was also with the engine at idle 13,7 volts
pic 4 was taken at 1934 rpm's 13.6 volts

battery voltage with engine off key out was 12.7 volts

so based on these picture when was the battery being charged or not being charged

There all charging exempt when it was off. Of course. From the pictures

05 Eddie 5.4 148000 bought it in 2011 with 105000 from what I can tell everything is original, only things that I changed myself were the plugs and cops. I'm gong to try cleaning the posts off and check the voltage

Its not charging when its idling

THEN HOW CAN YOU STATE THE ABOVE

FOR YOUR INFORMATION
• A functional charging system should produce between 13.5 and 14.5 or more volts while idling.
• A voltage of less than 13.5 means that your alternator isn't producing enough current to charge the battery.

Kindly post those voltages then we can better determine if the alternator needs to be replaced. Rather than just an un-informed guess

for your information i know this!
Stop being a a$$ about everthing i say

 

[Bedrck47]

if you know all of this then why did you say "Its not charging when its idling"

and then when you looked at the pics I posted you agree that all but the first pic showed charging

 

[Bedrck47]

Sorry if you think I am being an a$$ but when someone gives false statements It only adds to the confusion to the original poster

You stated to the OP " I'm positive its your alternator" but how can you tell him that without troubleshooting the system.

IMHO the only good advice you gave him was to clean the battery terminals.
you need to go back to school and learn or improve your electrical troubleshooting skills or leave those question to those that are better informed than you are
