how are the power boards tested with a dmm on this gottlieb 80a
I know on the stern and bally boards black on ground and red on tp1 etc. I don't see anything saying ground on this gottlieb board I am new at this just need a little help thanks
Pretty simple.
Look here: http://www.pinwiki.com/wiki/index.php?title=Gottlieb_System_80#System_80_.2F_80A_Power_Supply
In the picture, you can see that TP3 is labeled COM.
Black probe on COM (common).
Red probe on each of the other marked test points.
That's it.
