Please get those batteries completely disconnected. You may have an explosion if you don't... You may have also destroyed your truck start battery as well...
consider this wiring diagram for two groups of 6VDC batteries wired in series...
This is how 4ea 6VDC batteries should be wired.

If you wired them all in series then you are producing 24VDC to the 12VDC system.. That is bad NEWS... You may have burned up a bunch of 12VDC items that were connected when you hit them with 24VDC. Hopefully blown fuses or melted in two wiring have saved you.
You really need to have a multimeter and be using this to determine thing before you commit yourself. Hope all turns out OK for you...
Would also like to know what color of wiring you have around your batteries...
The RV WORLD uses BLACK for HOT or +12VDC and WHITE for GROUND or -12VDC.
The AUTOMOTIVE WORLD uses RED for HOT or +12VDC and BLACK for GROUND or -12VDC.
Sometimes these get mixed up since the battery is used in both worlds...
