thanks.i could manage without that feature,but would like the machine 100%
so is it dead or staying on permanently?
is there also one for the back box g.i's that u can swap it with to make sure its the triac not the triac driver?
have you checked the lamp that is connected to the scr is blown?
this is what marvin says about it (it mentions ms pacman but it should be the same)
"I am working on a Mr/Mrs Pacman, and I notice the GI (general illumination) lamps flash on and off at certain times during attract mode, but does not come on during game play."
To make the GI lamps flash on and off, Bally used a Triac bolted to the power supply board in the cabinet. The triac is cycled by the GI lamp flasher board mounted under the playfield. This flasher board is similar to a solenoid expander board. The output of a lamp SCR driver is used to drive a MOC3011 opto coupler that drives the Triac. As with the solenoid expander board, a dummy 555 lamp is connected to the SCR output on the flasher board to insure there is enough current draw to drive the MOC3011. Most likely this 555 bulb is burned out, and causing your problem. Also check the flasher board for bad (cracked or cold) solder connections. Check all the cable connections to the triac too. Lastly you can replace the MOC3011 chip.
