Got two machines yesterday one working (wet n wild) one dead (pac man plus) I swaped over psu from wnw to pacman but pacman was still dead, tried psu from pacman in wnw but no go so put the psu back in the wnw and turned on but the wnw is now dead also, I've checked the fuses they are good but got the multi meter out and theres no out put from the psu.
Could changing over the psu's fried the wnw board and the pacman board? could the pacman psu be a board killer?
I was getting no led light on the board.
Thanks guys i'd be very very greatful for any advice

Cheers
Nick
