Help! 1976 Corvette

[Montobeen]

I purchased a new battery about 2 months ago for my 76 Corvette. No issues until Saturday, I went to start it and it was completely dead, no lights on and this has happened before. What could be drawing power on the battery? Could it be the alternator (replaced 2 years ago)?

Charge the battery and then disconnect the positive cable and let it sit for a couple of days. If the battery is dead then you have a defective battery. If the battery stays charged then you have a parasitic draw.
