I was installing a rebuilt alternator and failed to unhook my battery – ya i know... when installing the battery terminal wire to the back of the alternator, I arc’ed it and saw a puff of smoke from the driver’s side on my engine bay – looked like front area. The back of my alternator has three wires. a number 1 and 2 terminal set and the BAT terminal that attaches to a post. It was the single positive wire (BAT terminal) that I arc’ed. I am not reading 12 volts at the BAT terminal on the back of the alternator. I have no power to my ignition switch – truck will not start. I do have good battery power. I also have no voltage at my ignition fuse when measuring against ground. Other fuses location such as horn have power. I obviously smoked something. Need help.
