further update with power on and board disconnected using the (music note setting for continuity) on my meter measuring from the power supply to the pin on the edge connector i have the following
my pin numbers ...
: pin 14 ground
: pin 4 -5
: pin 5 ground and -5
: pin 16 12v
: pin 14 -5
: pin 16 -5
: pin 18 -5
: pin 18 +5
: pin 16 +5
seems odd to me some pins can have cont at ground and also -5 ? and so on ?
all my pins are backwards to look at which doesnt help , ive managed to match wires ok on new edge connector put put the numbers on the wrong way round
so pin 18 ia actually pin 1 and so on to confuse further

looks like either you have the edge connector wired up wrong or you are not reading it correctly
i havent touched the edge conenctor ? ive only copied where the wires go ?
on my other midway the wires are in the same positions ?

i will tell you one thing though,if you wire up minus voltages wrong you will most likely blow the shit out of the game board
when ive taken the cont readings today i havent got a gameboard installed and i wont . as ive just forked out alot of money with irongiant to have one fixed ?
meter readings again today from supply were :
-5 5.00
+5 5.01
12v 12.00
and on ripple setting
-5 0.00
+5 0.00
12v 0.01
when i did cont readings no gameboard was installed and i was taking readings from power supply to pin inside edge connector
i only have togo on the cabs i have before me , seems odd they both wired the same ? and neither work , just show a white screen ?
thing is too , i can only go on what the seller told me and he said one worked and used to play it then one day didnt work
so i persumed neither had been fucckered with ? infact i still dont know if they have / i cant see any loose wires and they all seem to be original wiring ??
anyway got a bog standard midway si they can show me pic of there edge conenctor please?
again all ive done is copied the pins and there spacings inbetween ?

albeit with the edge connector numbers and letters upside down
