Issue 1: I presume the champagne kicker is immediately firing upon power up. If that is the case check Q4 on the ppb for a short.
Issue 2: You are correct, sounds like you're not getting the low power voltage. There should be a schematic of the solenoid power in the manual.
Issue 4: Go into switch test and see if the switches are working. Check for bad bulbs.
Issue 6: Clean and reseat all connectors to the board (both ends). Reseat any socketed chips on the board. Make sure the board is properly grounded (all of the mounting screws installed and tightened).
