2001 Ford Thunderbird engine wont crank just clunks

2001 FORD Thunderbird mileage: 65,000. The engine was running a little rough, so I pulled plugs and cleaned/re-gapped and put 'em back in. Replaced #2 and #3 plug wires, no change. I then replaced cap and rotor. And then it happened. I must have put wires back incorrectly on the distributor cap, because when I tried to start it, pop pop etc. I got out the book, checked the firing order, direction of rotor rotation, (what I should have done in first place) But now, when I turn the key, nothing, no movement at all! No cranking, no click, click, from a dead battery; nothing but a clunk like sound seemingly coming from the vicinity of the ”High Current fuse Box”. Did I blow a fuse/circuit breaker? Or, Is the engine frozen from the timing chain breaking because of the misfiring from my bungled plug wiring? Battery is fully charged, Interior lights are bright etc. HELP!
