The old power supply in my Gaplus had a -12 but the switcher I got from Bob Roberts doesn't have -12 , what do I do . Its the purple wire in the pic .

Try attaching it to the -5. It's probably just used for the sound circuit, which normally takes the +12 and -12 and rectifies it down to +5 and -5 anyway. At least, that's how Williams games do it. Hooking up the -5 will work probably....
According to the Gaplus manual posted at arcarc (not a very good scan I might add), this game uses an MCR power supply and it generates a reset signal to the game board. It does not show a switcher power supply.
On the old power supply there is two +5 outputs , +5 20A/OVP and +5 RTN . Can both these go to the +5 on the new switcher ?
So I hooked it up and the voltage at +5 is too high , 6.6 and its turned all the way down . Also I tested the AC input at the switcher and its at 60V , shouldn't I read 110V there ?
The +5 RTN is ground. RTN = return...
When reading AC voltage, you put one lead on one AC input and the other lead on the other AC input. If you have one lead on ground, you'll only read half of the AC voltage...
take it off and hope your board is okay...
That's what a degausser is for...
Everything is ok and working 100 % !!
Damn making a mistake like that really sucks .
The monitor looks great , I rebuilt it , but I am having major interference thats washing out the colors when its put back in place . I've read on here thats a common problem with cocktails ,
