ok heres the story. I bought a working pacman off CL. aboout a month goes by and it stopped working. i thought it was the board so i sent it out to my board guy and he tells me the board works perfect. he thinks its the switcher thats wired in thats bad. So i ordered another used (i know) one off ebay and it arrives a little different than the one that was in so i go to look at the pictures i took on my digital camera and half my photos are wipped out...some luck! so can you guys help tell me where to hook up the black and white wires to gett him working again. Thanks

ok heres the pictures

what the monitor looks like

where the black and white wire go:

That wiring looks like shit, with the exposed wire ends like that. Clean that up when you put the new switcher in.

This is the easiest (and best) way to connect a switcher to a Pac board if you're going to direct connect:

thanks for that but thats like a foreign language to me. i have a black and white wire that goes to the bottom of the switche and the same colors that are soldered to the board that i dont know where they go. Could you explain to me where to put them? thanks
 
GND goes to Ground > from the Switcher to the spot on the board in the pic
+5 goes to +5 > from the Switcher to the spot on the board in the pic
+12 goes to +12 > from the Switcher to the spot on the board in the pic

The Black and White wires on the switcher in the pic are for powering the switcher....

Test the output levels on the switcher before you apply any power to the board! If that switcher is bad, or outputting more volts than it should, you could fry your board.

The knob on the front there is for adjusting the 5v line... make sure it's at +5v!

Disconnect all the wires soldered to the board.

Then get three new wires of different colors. Attach one to one of the GND lugs on your switcher and the other end to the board where it says Ground in that pic I posted.

Do the same for the +5 (from +5 on the switcher to the spot for +5 on the board) and +12 (from +12 on the switcher to the spot for +12 on the board).

Leave the wires going to the AC115 spots on the switcher.

If your monitor, board, and switcher work, then the game will now work (with the edge connector on)...
 
Also you are pulling the 115ac before the filter, shouldn't make much of a difference. Then you are screwing to bare wire, instead of using spade lugs to connect to the PS terminals. The Black and White wires are common colors for standard in wall wiring for 115vac, should use brown and blue, and your wire gauge looks a little small.

Having a white and black wire soldered to the board, in an unclear picture doesn't help us to determine where in fact those wires are going, since they aren't supposed to be there anyways, and are the wrong colors.

So by cleaning that mess up, and putting the correct wires to the edge connector, then to the correct spot on the PS will eliminate future confusion.

I didn't notice that. THAT needs to be changed. With the 115ac being pulled at the filter, that means it's out of the power switch loop, and will stay on all the time that the cab is plugged in. That will make it die a lot faster than anything else in the cab. The power for the switcher SHOULD be tapped into the bottom lugs of the isolation transformer...

This is a United States Versus The World thing. We use Black hot, White neutral here. It's not just in-wall wiring -- Black/Green/White Hot/Ground/Neutral in a 3-pin molex for carrying AC seems to be some kind of de-facto standard as I see it all the time in factory wiring on machines as new as 2007.

The gauge is fine if you're not drawing much. If the wires are actually rated for 130V or better (US, mind you), I'd say leave it.
 
Guys.. he can leave the wires as-is..just as long as he connects them to the correct terminals on the switcher. He is an admitted novice..don't tell him to de-solder anything since the game was working fine before the ps died.
