Update tonight- no closer


* I re-tested that diode on the 1 x lamp  that I thought was dodgy and it tested fine- must have been me last night- I checked all the diodes on the appropriate bulbs again tonight and they ALL checked out fine with a 560ish reading one way and NIL the other.


* I removed the flat data cable and replaced it a few times, swapped it around – no change at all.


* Refer to the Lamp Matrix below to check that I did the correct thing here - I put the MM on continuity and I held one probe to a Column 1 lamp wire under the playfield ( Left Outlane ) and I held the other probe on a Column 8 wire ( Mystery ) and I got NO beep noise. I also did this with a couple of other 1 and 8 lamp combos to triple check it – no beep noises at anytime ( I did check my MM by touching the probes and it was functioning and beeping when I did that ) . I was also unsure whether to do this test with the machine on or off  so I did both and if it was meant to be off for safety , I am still alive 





So I decided to make exact notes of whats going on and show a pic of the lamp matrix below and the issues I have.
Here is whats happening in the Single Lamp Test
( using Column 1 down as an example )

Shoot Again( Column 1 ) - Lights with Light Extra Ball (Column 8)
Kickback ( Column 1 ) - Lights with Light Advance Raft (Column 8)
Left Outlane ( Column 1 ) - Lights with Mystery(Column 8)
Left Flipper Lane ( Column 1 ) - Lights with Boulder 5X Award(Column 8)


If you then go down column 2 and realise that
River R1 ( Column 1 ) - Lights with Light Extra Ball (Column 8)
River River 'i' ( Column 1 ) - Lights with Advance Raft (Column 8) etc etc etc and repeat that process for the first 4 lamps down EACH column then you should get the idea.

In other words the lamps marked with BLUE in each column 1-7 - light up with the corresponding lamp marked RED in column 8.

Obviously Column 8 is causing my grief?
