2007 dodge ram 1500 battery gauge fluctuated and check gauges light on

Asked by Shirley Apr 23, 2018 at 12:44 AM about the 2007 Dodge RAM 1500 SLT Mega Cab 4WD

Question type: Maintenance & Repair

I don't know a lot when it comes to vehicles but i
have been trying to learn so I am putting this out
there hoping someone might help....the lights on
my truck had been left on for about 6 hours, I
went started it drove about 2 miles parked,  
noticed that the lights were on and that the
battery was on the low side not really low tho.....i
turned my lights off and started it again it fired
right up but the battery indicator kept moving
from half to the last bar before red. Then the
check gauges light came on. I stopped at
O'Reillys and had them hook up to see what the
light was for they said I needed a new
alternator...bought and installed, didn't help...put
new battery in it seems to be stable running at
11.3v-12.0v. but the check gauges light is still on.
I have checked fluids and so on but everything
seems to be fine. Is it my computer..belts...i do
not know any thoughts??? Please

Most would add a gauge instead of just a light to measure power production. Lights are not very accurate and often come on only after a problem...

If "Battery INDICATOR Moved From "Half",To Last Bar Before "Red", That Sounds Like a Voltmeter GAUGE,Right??
