lost power to alky, a/c and blower motor?

[QUIP'6']

always something here with these damn cars. i got my motor up and running and went on a warm quiet maiden voyage and everything was going great. kept the car out of boost and cruising like a sunday driver. then to my surprise the car shuttered for a split second and i lost my blower motor. then i noticed my alky light was out. so i checked the ignition where the alky was plugged in and i have no power. the battery slots i have power. could this be a fusible link to the starter? and if so why? thanks

well i found the problem it was the fuse under the dash so i changed it and then i checked the pressure switch plug behind the ac compressor and the wires were super hot so i unplugged it and the female slots needed crimped tighter so i did that and plugged it in and the ac kicked on and the wires were cool. why would the wires get hot when it is unplugged and the ac switch turned on?
