If the battery light is still on you may have a bad alternator. Recheck the charging system. If it's around 14.6 volts then key on engine off. Unplug regulator plug from alternator. If light goes off, try another alternator. If light stays on, check for a short to ground. There is no reset for this light. It is controlled by the alternator. The regulator could have a short through it but could still function properly.
