Hey guys I'm new here so I want to thank ahead for any help on my issue. I just picked up a 1989 4 cylinder Hatchback as a project about a week ago. Drove it home and it was fine but three days later I came back to it and it wouldn't start, no crank, no click nothing but the lights, cluster, and interior stuff would work. Now I checked the battery and realized it was low so I bought a new one. I put it in but now I have no power whatsoever. I get no power to the lights, hazards, windows, locks, or anything. I tried turning it on by jumping the starter solenoid terminals and all I got was a click and it doesn't always work. Did I accidentally blow like a main fuse? I check the fuse box and all the fuses seem fine. Also when I picked up the battery I tested it and it read about 14v now after trying to start it it reads 12.3v, so I don't know what that means. Any help would be greatly appreciated, thanks!
