    If it is on, you most likely have a code stored, so that has to be addressed before the EPC light can be turned off. If you disconnect your battery negative cable, with the key out of the ignition and the doors closed, that can sometimes clear the light, if it does not, you need to have the EPC code cleared. Sometimes replacing an Alternator with out both Battery cables being disconnected can spike the EPC computer and it may need a re-calibration, not some thing a 'home gamer' can do.
