Question from Tony: Hi,
I am a collector but I never knew how to fix them until I saw ur site, I just wanted to say thank you for hosting a site for novice collectors like me.
My problem is I had a old ring king game that has been sitting for a while I checked the old power supply and it was not working at all so I ordered a new happs switching power supply when I got this I noticed the +5v/7a is different on the new one it is +5v/15a instead. Also the +12v/1a is +12v/2a is this the wrong power supply? The issue is when I plug in the game the fuse blows in the fuse box coming in from the cord? Maybe the cord? The Cord is pretty old but I didn’t see anything wrong with it.
Thanks for your time
Tony

Response from Jonathan: Tony,
It’s perfectly OK to have a power supply that has a little bit higher amperage than needed. Sounds like your new power supply is actually a little better than the one than you pulled out of the game.
Blown fuses in the bottom of your game are usually caused by bad wiring. It could be your cord or a problem with some wiring inside your game. It could also be some feedback coming from your board. It really depends on what line the fuse that’s blowing is located on. If the fuse is located on the AC line going into the game then it’s probably a problem with the power cord, isolation transformer or power supply wiring. If the fuse is located on one of the DC lines, it’s could be a problem with the wiring inside the game, board or power supply.
Hope that helps, Tony. It’s really going to be more of a trial and error process. Just look through your cabinet and examine any wiring that’s frayed or disconnected.
