So I was driving today when my maf and coolant temp sensor wires were ripped after contact with the water pump pulley.. While it was happening I noticed my battery voltage fluctuate a bit then suddenly shoot down to like 9.0V or so before I shut it off.. I pulled over and fixed the wires, but now my alternator only charges up to like 13v... On the way home on the highway, the battery voltage fluctuated between 12.6V and 13V at a steady speed.. Is my alternator fried due to trying to provide more current than it could when the wires shorted?
