Gottlieb Genesis Fixing for a friend, he has installed new mother board and power supply board and done some ground mods. When I first got machine it allowed me to play 11 or 12 games shutting down during 3 of them. The more it's played the faster it shuts down to the point you can't get through 1 ball. I'm an EM guy looking for any direction or help where to look next.

You suggest repinning connectors? Or would you replace harnesses if available.

Quoted from NickyVanHalen:

The wiring harness itself is probably fine. The connector pins can sometimes be worn out and dirty. Although, I found that to be more of a serious issue on system 1 gottlieb games than system 80 games. Still, it's worthwhile to do a visual inspection of the pins.

However, before you go through the trouble of repinning, what I always do is clean all the edge connectors on the boards. Rub all the edge connector pads with a pink rubber eraser to remove grime and tarnish. Others have suggested sandpaper or fiberglass erasers, but I always recommend the pink rubber eraser since that is the least destructive approach that also does a very good job with cleaning.

UPDATE found broken diode on coil, another coil had been replaced w coil w no diode (should have had 1) and a bridge rectifier w loose bad solder. Game is now working except the Genesis figure that should be revealed when u earn it is always revealed I get the light show and change of music. I'm sure the cannister? Should be covering it then rotate open to reveal. I can't get past memory in test mode (is this because of new board?) Not sure how to get that final part working.
