Hi was wondering if any one can tell me what voltage readings should be at the connector that hooks on the cpu board coming from j4 I believe? I think I have a low voltage problem just not sure some graphics appear on screen but will not go any further. Game was working last time I used it.Now it always boots up to same graphics and will not go any further. ay help or suggestions would be great.

THANKS
 
Hi every one I have a update to my posting. Here is what I found for voltages at the connector to the boards.

going from top to bottom

first four red colored wires 5.07
next four wires are yellow and black striped or maybe white with black striped.
all of these are 0

next is a grey wire it reads 5.62
followed by purple reads 0
the orange wire reads 11.60
and last white and its 0

hopfully somone can tell me if these voltages are correct or not .

THANKS
