American Spirit - Glass lamps light up. Bill changer initializes, or at least makes the same sound it used to. No Dotmation lights come on, reels do not make a test spin. Candle lights are off. Fail light on I/O board is OFF. The 5 power supply lights on I/O board are lit. Voltages on the I/O board corresponding to the lights all look good with a voltmeter. Re-seated both CPU and I/O board, and all connectors I could find through out the machine. Re-seated all E-Proms. This issue has been occurring for some time, but after removing power, and turning it back on it would operate fine for as long as I played it, till it was powered off for a few days, and then powered on again. Then would have to re-cycle power to get it going. Now power cycling does not do the trick. Any ideas ?
