Ok. This sounds very much like a battery issue.. Assuming a plate has not failed inside the battery (which would cause no current to flow). You might have connection issues.. Can you take the battery terminals off and see if there is corrosion on the battery terminals and the battery posts? Also see if one of the clamps on the battery terminals is loose. A 12 volt DC testlight of DC voltmeter would be really handy here if you have one or can get one.
