So are you looking for a generic 6 volt battery hookup diagram or are you asking another 1993 owner for a picture of their actual battery setup? You can check out lots of info on the net for battery hookups for example:
How Do I Connect 4 Six Volt Batteries To My 12 Volt RV House Battery System
Do you know if your batteries are good/charged? I would suggest also buying yourself a cheap digital voltmeter (if you don't already have one) and check those 6 volt batteries for state of charge. Battery cell acid/water levels might also be worth checking....carefully. Battery acid loves to eat through clothing.
