TILT Codes WMS Big Bang Piggy Bankin Slot Machine

[formertexan]

I just got back my Big Bang Piggy Bankin 5 coin Slot machine (Model Williams 40S5) that I had stored at my friend's home.  It was working when it left my home.
NOW, when I turn it on, I get the code battl.  I've opened the main door and in the card cage where the 2 circuit boards are ALL 5 red lites (LEDS) are lit.  At the far left of the same board, there is a red LED lite that is also lit. When I bought and received the machine years ago, the card cage door was open and the wiring had been rewired.  There is a push button switch wired to the wires and two of the wires are not connected to anything.  There is no diagnostic button. 



 
If I push the push button switch by the cage door, I then get a tilt 5191.  Does anyone know what this code is?

Install a new battery on the board.
