Hi Larry, thanks for the request!
If the ac was being called to run while you were fixing up the wires outside and the two wires providing power to the compressor contactor touched each other, then yes it's possible you either blew a low voltage fuse or possibly shorted your low voltage transformer. Both of these are located inside the indoor unit. If it's a newer model (last 15 years or so) it should have a fuse and it will be a purple 3 amp ATC fuse. These are the same fuses that automobiles use and you can find them at any auto parts store. If there was NO fuse in the indoor unit, shorting the wires would have blown the low voltage transformer in the indoor unit.
If you have the make and model number of the indoor unit, I can most likely tell you if you have a fuse or not. On rare occasions, the fuse is a yellow 5 amp fuse, usually it's a purple 3 amp fuse though.
