System 1 Atari ,how to power amp from switcher ?

- Start date
ah still the same .its not liking something
The red 12v low ,definitely to ground ?
I’ve just traced the orange wire from the connector going to the audio 2 board
It goes over into the game boards ,same connector ,same hole as that other orange
Is it some kind of loop in and out maybe ?

Measuring at the connector the orange is getting 0
The red pin second down is showing 13v without load
Atm that orange wire. the 18v that was on transformer previously is only gong to one side of a fuse block with nothing in other side of fuse
From the 12 v on the switcher
It’s not connecting up with anything

Thanks for your patience
That orange wire goes straight to the game pcb block connector
Where there is 2nd orange wire coming out of exact same point on same connector .
The lose wire is coming out and going nowhere
If I send the 12v to that lose wire from switcher
Would that supply the main board and the audio board the 12v
As that would be a loop of orange wires
Into pcb and out to audio board
Or should I remove the orange wires from pcb ,so that the 12v is only going to that audio board ,directly from the switcher .
Not to pcb

It's hard to tell what's going on what's not connected, but the game pcb is already getting 12v so that's fine, you need to focus on getting 12v into the orange wire in the picture above that goes to the amp.
Just don't connect the 12vac from the old transformer if it's still installed to the switchers 12v, as it'll kill the switcher.
Continuity / beep test on your multi meter will tell you if the above orange wire goes where you think it does if you cannot see exactly where it's going.
