I can tell you right where the short is.....
IT IS RIGHT THERE......
Negative to positive and negative to positive will get you NOTHING but Heat...
It is a pretty safe bet that nothing got hurt because it was dead before it go started. If you have anything at all, then one jar has been successfully charged backward.
I will have to suggest that both of the jars (batteries) are only good for a core deposit at this point.
Get an new pair of Grp 29s and strap them in parallel (Pos to Pos and Neg to Neg) or a pair of GC2 (6V golfcart) and strap them in series.
