I had the carpet replaced in my 1980 vette, now I am blowing a 15 amp fuse that lights my choke/amp-battery dash light, and the tach now doesn't work. What wire has been grounded, as when I tested the alternator, it still is charging the battery aside from the idiot light now on on the dash ??? Please help???

I HATE it when that happens!
That fuse goes to a relay for the choke. From there, it goes out to the choke itself, and also the the printed circuit board on the gauge panel. Sounds like a wire got pinched in there somewhere, probably up around the console area.
If you pull the carpet back out(or just back), you would be looking for a Dark Green w/White strip wire, or a Brown(there are two browns that come off the relay...one goes to the circuit board, the other comes from the fuse box) wire pinched, or shorted in some way. These wires will most likely be in the center console area, around the radio.

This is assuming, of course, the the choke itself isn't the problem. Try unplugging the connector on the choke, and install a new fuse to see if it still blows. I've seen many 'lectric chokes over the years short out and blow the fuse, for no apparent reason. Just co-inky-dink.
