Chime Not Working on Vista 20P

I believe I have the Vista 20P, and recently bought a new battery. When I installed the battery, I crossed the red and black and it sparked and I noticed once I got it corrected, my keypad LCD was messed up and there was no chime when opening doors anymore. So, I bought a new 6162RF to replace my old pad from 2007, got it installed and still no chime. I worked my way through getting the installer code figured out and being able to clear a trouble code by disabling it, and also got my low bat message cleared, but still no chime. Today I messed with is some more. I tried installer code+9 and it toggled it off. I hit installer code again+9 and toggled it on, and it doesn't beep when opening doors. I tried going into installer code + *26 + 0 and it beeped and showed "00". Exited and tried the door and still no chime. When the door is open, the pad shows the zone fault just fine, it just doesn't chime. Would anyone have any step by step actions I can take to try and get this working or do you think I shorted something out in the board that works the chime when I crossed the battery leads? Thanks!
