Help! Intalled the dash today and before I finished I checked for power. Everything worked fine. I disconnected positive and put the radio in. When I checked again, the positive battary terminal sparked a little and now no power. The two wires, yellow and gray, to radio was touching and might have been the cause. I checked all fuses and they are fine. Battery checked and fine. This happen twice before during normal driving and 8 months ago and a few days later just worked. No clue why. Could there be a fuse that resets itself?? See link below for past issues but almost a year ago. I would love to drive the car as its been sitting for a few months while I worked on the dash. Where should I check for 12v power to troubleshoot it? Checked and no power to fuse box.
My guesses would be either (1) bad connection in firewall connector, or (2) fusible links OR wire going open and then making contact again. Whichever will require some testing with a VOM.
