I'm experiencing the exact same issue with my '73. It ran fine until I had a battery short out Sunday due to a long period of storage and a quick charge. I put in a new battery, and just like grnsky, I have brake lights, but no activity on key turn- no fuel pump, no anything. Also no headlights, running lights, dash lights. But the brake lights work! That seems to point to the ignition switch I would guess, but it's odd that all was well and now I've got nothing. Fuse block has all good fuses, I can't find any inline fuses, and it doesn't appear to have fusible links like my '74 had. Let me know if there's anything else to check or if I need to go through the painful circuit by circuit process described above... thanks in advance Dan
