I am working on a couple things on my Getaway (beacon motor sometimes doesn't turn, accelerator board doesn't always boot up with power). I was reviewing the schematics and comparing them to how my game looks and wanted to confirm whether mine is right or not.

On the upper right corner of the power driver board, we have J104 and J105. As you can see in the photo, mine was the red/white wires connected to J105 and these go up to the TRIAC board to run the beacon motor. The blue/white wires are connected on J104.

The schematics in the manual seem to indicate this should be the other way around, so that the red/white wires are in J104 and the blue/white ones are on J105. You can see this on page 3-16 of the manual where the Triac Driver Board Assembly is detailed as well as on the next page, 3-17, which has the details for the "revolving lamp circuit" at the bottom. Further along on page 3-22, it has the Power Circuit connections list and under the power driver board section, the last line is for white/blue Flipper 50VAC saying it connects to the backbox at J105-1,5.

Can someone confirm which is right? Do you have a picture of the connections on your own game you could share? Much appreciated!

Ok. I follow. Power source to J104 is the same as to J105. Pin 1 to pin 1, pin 2 to pin 2, etc.

The connectors though are not the same. Looking at the board as we see it, pin 1 is on the left to pin 5 on the right. So it seems like our blue connector uses pins 1 and 2 while our red connector uses pins 4 and 5. If the sources of power are not identical and come under different loads at different times, wouldn’t this make a difference?

Thanks. I made the change. Game starts up fine and plays fine too. I did the flasher test and those all come on in the backbox and on the playfield.

Something intermittent still going on with my game though and related to the supercharger. Every so often, seemingly on the first or second game after powering it up, I get like a phantom start of the supercharger where the sound effects get going briefly and it thinks you shot the ball up there, but you didn't. I read somewhere else about the wiring connections getting loose on the opto pairs and I am thinking this could be happening. I am going to test it by running a game with the glass off and then while I have the ball in hand, breaking the opto beam with a pen tip and seeing if that same phantom thing happens. Previous thread talked about how the vibrations can sometimes make those optos act strangely, especially if the soldered connections aren't perfect.

I am thinking it is the ramp entrance opto pair that's suspect as it thinks the ball goes up and starts the loop. Of course I can watch for the diverter arm and see if it swings open. It could be the 5th opto pair too on the outlet of the magnet section confusing the logic as well. Those two are easy to test as nothing has to come off other than the glass to interrupt the beam.

The beacon motor thing was always intermittent, so it'll take more games to keep monitoring it to see if it sticks again. Easy to say it's fixed because it isn't doing it again right now... until it does it one more time and then you know your solution wasn't the one you were looking for. Intermittent problems SUCK, lol.
