Battery Light "on" ?

[blowinsmk]

Hi and thanks for all the welcomes! --- My battery light comes on after starting and sometimes stays on and sometimes comes on after starting then goes off after a few minutes but will usually come on and off intermintently-the batteries are new, the alternator is new, and i checked all the grounds i could find and they all checked ok. I am kinda stumped any suggestions? thanks in advance for the help!!

have you checked the connections at the battery terminals very closely, and also checked the resistance through the wiring??

thanks mark-- i cleaned the connections thinking that might be what it was but it did not help--- excuse my stupidy but what do you mean by checking resistance thru the wires

you will need an ohm meter. Disconnect the wires to "isolate the circuit" then measure the resistance from point a to point b. resistance should be VERY low, and honestly in a wire that big, it should be 0 ohms

just a little thought take a volt meter and check if there is 14 volts at the battery when the truck is running. if not then take a test light and connect it to the battery ground then connect the light to the red and black wire that connects to the alternator bye a 12mm or 1/2 inch nut the wire is pretty thick. and if it does not light up the test light then one or both inline fuze wires blew out. you find them on the passanger side of the vehicle and they will be connected to a circle thing with two bolts sticking out of it nest to the battery. follow those wires and if the inline fuze burned up it will stand out. just go to carquest or a parts store and buy more linefuze wire and splice it into the wires where the old stuff burned out.
