I have a great condition Stern Stampede that I just purchased from a gut who has had it probably form the start. It was his grandfathers and he remembers playing it about 30 years ago. Has 33,000 plays total.

My issue is the second fuse down from the top in the five fuse stack keeps blowing up as soon as I hit the credit button to play. It is a 15 amp 30 v spot. I am not pinball savy or electronic savy to boot. Is this an easy fix and or where should I look to diagnose the issue. I have no manuals with this machine. I am very interested in purchasing more in future and would like to begin learning basic fixing up on the machines.

Thanks for any and all help here,

Jim

Thanks and just added a picture of another unit for help off internet and learned more as follows.

The fuse blows right after I plug in the machine and fire it up hitting the credit button. I put a stronger fuse of 20 in it and it and when doing the same procedure I blew the first fuse on top now. It appears when the game is firing up after the credit button is pushed is the cause. The fuse that blows has a white with green specked wiring. Is it possible to trace this wire to the issue? I have included a picture of another stampede from the internet to help and....!

Just traced the white wire with green specs and it goes all the way to the back of the bottom of cabinet to a larger device in the center of it. See picture and you can see the device or unit which is the largest in the center of cabinet back bottom. http://www.ipdb.org/images/5232/image-13.jpg
