Lights, but no fire!

[72superBB]

Ok, I pulled my dash bezel and installed my camaro tach in it.

I put it all back together and now I turn my ignition key and I have power, but there is nothing else. No clicking, no engine turning over, nothing. I ran the battery down because when I pulled out the headlight knob, I did not realize it turned the lights on and stayed on.

So I have it on the charger for tonight, but if that does not work, then where do I start?

Any ideas would be greatly appreciated.

Thanks

Ron
