Only once did I have a battery cranks about 1/2 second then all was dead. The battery had an internal open circut. Very dangeroustoo. Usually tis blows the top off the battery when it sparks the open circut. I don't think you have this on 2 batteries. Check all the positive and negative cables on both ends. More info needed like horn works or lites work.... Or not...
