The single coils look OK- even if you'd borked the HB, you'd still hear the singles.
-Is the volume up? If I had a dime for every time this was the problem...
-Check for a loose ground wire- it's fairly common for wires to come loose when you're working on other stuff, I was just putting a series/parallel switch in my Tele last week and it came up dead when I put it back together- the ground wire to the output jack had come off.
You can do this, just hang in there!
