So I think I have sorted out the lower playfield issue.
After beakys magic touch it is all working.
This is a lesson in triple checking. I found that some of the harness wiring was connected to the wrong plugs (on the harness). I never really checked the machine when I bought it just thought all the plugs were plugged together so they looked fine.
What I found was the aux lamp board cables on the back of the back glass door were connected together. So the CPU was telling the aux board to do this and that which was fine, but the cabling was basically back feeding itself and blowing up the ic chips on the aux board.
The cables were in a mess tied up so never noticed plus the other ends were also joined together and sitting in the bottom above the speaker so I never seen them till I started fishing around.
So lesson learnt double even triple check.
So it's great to have a fully working machine now just a bit of tidying up to do with the harness and straighten a few switches and bingo done.
Not sure if I will paint the cabinet tho as its a lot of work I did notice they have stencils now for this machine.
Thanks heaps every one for your tips and advice.
Also a big
thumps up for beaky the magician.
