I was replacing my stock 80 amp alternator with a remanned high output 100 amp type (140 amp). When I was moving the wiring from the old alternator to the new I forgot to disconnect the battery and I touched it to the block with my wrench and caused a popping short. But wait there's more, when I did finally get it all buttoned up after disconnecting the battery, I go to reconnect the battery, and the ground and power wires burn through microcracks in each other's insulation and cause shorting for about 10-15 seconds before I realized. The alternator now holds at 13.4 and goes up to 13.6 when I blip the gas. I asked my mechanic friend and he said I probably fried my voltage regulator but the internals of the alternator should work given a new voltage regulator. So I was just wondering you guys think the internals of the alternator are toast or just the regulator. Any input is appreciated
