I recently bought a 78 280Z in great shape although now I am finding some electrical issues. My heater blower will run for a while (a day or two) and than irt blows the fuse. I have also noticed that the power antenna does not go up anymore when I turn on the car. Anyone have any idea how I can start tracing the wires to find the short? I am more into computer software than auto repair but I'm not a complete idiot

 

Start by tracing all your grounds. Sounds like something is lose and causing a short.
