So i go to start the ram and it sounded luke the battery was bad. Then it started fine. Looked at the jnstrument cluster, check gauges light was on. Battery had full power, gas gauge said i had 1/4 left...but im actually on empty. Now gas gauge is reading normal but check gauges is still on and every few startups it soundslike its not going to turn over but it does. Anyone know whars up? 2007 1500 slt qc

 

Either your battery is not holding a charge and/or your alternator isn't charging properly. I'd go to a local auto parts store and have them test your battery and alternator.
Starters draw lots of juice, so that will show a weak battery. I'd guess battery, hopefully, as it's the easiest fix.

Use THIS site if you are handy with a meter.

 

i read that running on empty can set off the emmisions/gauge light. maybe this is it? idk but the truck seems fine now other thn the light still on. will it clear by itself?

 

Get the alternator checked.

 

Also might wanna check for corrosion on your starter cable or ground.

 

everythings fine now. guess it was just out of gas, filled up drove it light went off and everything's good.
