Ok I picked up a Bally 1090 and the machine was dead when I got it, it had been re-laminated and the laminate was peeling, so after tearing it all apart and striping the outer laminate and putting it back together I found several broken wires and bent contacts which I fixed, I cleaned all the contacts and wiper board and it fired up, the only thing is that the upper cabinet lights did not come on or the insert coin or coin accepted lights. After looking everything over for several hours I did not see anything broken or cut, I had checked all the fuses before I started and all were good...
Then I noticed one of the fuse caps was different on a 5V fuse holder, I switched it with a matching fuse holder cap and the lights came on, even the coin in and accepted lights, but after a few minutes the coin in and accepted light quite working again, and now I went out to work on it tonight and the upper cabinet lights have quite working also, all fuses are still good, any pointers as were to start looking for trouble....
Thanks
