The chip could have come from one of several sources. what are the markings?
It sounds like you could have a charging problem. It's not uncommon for the alternator wires to fry themselves.
Take a look behind the battery tray and look for 2 or 3 yellow wires. There'll be a connector/s of some sort where the connect to the regulator loom. Chances are these will have fried.
Cut them back and fit new connectors. Wrap them in tape to keep them clean.
