refluf136

Been having some electrical issues with my truck which I originally thought was the ecm, replaced that and nothing, turned out to be a loose wire under the fuse box in engine compartment. I got that fixed now truck runs and drives back to normal, with the exception of the battery light. Battery is new, I have 12.6 volts off and 14.4 running. Battery light flashes the entire time it is running, I have continuity between the plug on alternator and ecm. Im not sure what else to check or what to look for, not sure if this junk yard ecm could be the cause. Any help or direction is very appreciated, thank you.
