The message center flashes a battery picture 2-3 times and then goes out. This happens about every 10 minutes while driving. Battery was replaced and the voltage after setting over night is 12.3-12.4. After start voltage goes up to about 14.4-14.6. Battery terminals are clean and I cleaned the large wire at the back of the alternator. Driving and starting all seem fine.
Thanks for the info. I don't have a scan tool but have ordered one. I also cleaned the connections at the red junction box and reseated the small 4 conductor connector on the alternator. I looked clean. I am monitoring the voltage wit a DVM plugged into the cigarette lighter and after the cleaning, it is working better. I noticed that when the light was blinking (after 2 hours of operation), the voltage dropped to 14.1. I happened to change from Auto 4WD to 2WD and the light went out and voltage came up. It has been working fine after. I will get the codes and let you know. Thanks for the help.
The final update is that all has been working fine for the last several days and no Battery light, voltages are fine and the truck operates fine. I did check for fault codes and none were found. Must have been coincidental with the problem clearing when I changed the 4WD controls. Thanks for your help.
