BV/SERIES for Bally

[lakwen]

So, I picked up a couple machines at a garage sale.

IGT Double Diamond
2003 Bally 7 Double Jackpot
2001 Bally Super 7 Blazing

I got the IGT running (thanks to this site through google...asking lots of questions)

The 2003 I put a new battery in and put new clear rams in and now I cant get the BV (WPA-13) to work (I can hear it at startup and see the red light through the side) I dont have any codes.

The 2001 How do i tell what series it is....I have to get new clear chips for that one also.

ANY AND ALL HELP APPRECIATED

Make sure the coin mech switch on the front of the MPU is in the up position. If it's in the down position it turns off the BV. Can you post a picture of the other machine in question?

i checked that and made sure the swithes were right (5 & 6)
