Hello folks,

Replaced transmission in sons car two weeks ago...car is running well, no issues. Battery light pops on, figured it was voltage regulator in alternator, it was the original, sooo obvious choice. Checked the fuses, not all, but most and found nothing. Changed the alternator, light still on. Changed the ELD, still on. Swapped out a known good battery from my other Honda, still on. Starting looking through schematics to figure out what turns this light on, can't find anything here: https://drive.google.com/file/d/0B4b...1XNGRndDA/view Pulling the cable off of the alternator with car running, light is still on. Seems like all the threads dead ended with no solution. Any help would be greatly appreciated, gotta get this car back to son as he is in college.

Oh and voltage at battery stays consistent at 14.57, and turning on lights and air conditioner, drops slightly, but voltage holds.

Bad ECU? Multiplexer was replaced about a year ago with Honda OEM
