Gottlieb Operation: Thunder (Gottlieb, 1992) problem

[richchodo]

when I get an extra ball the extra ball lite inbetween the flickers doesn't go on. It worked when I first got the machine. Its not the bulb. I have everything else working. Any suggestions? I do have a schematic-manual

Are you talking about the SHOOT AGAIN indicator? Do you mean; by "Its not the bulb. I have everything else working", the extra ball is actually served, only the lamp is out?

yes im talking about the shoot again lite and yes the ball does get served, just the bulb is out. I replaced it. I have everything else on the entire machine working

Good you have the schematic. Gottlieb refuses to let us share them. First check for volts(6.3 Vdc) at the socket during lamp test. Nothing, or close to nothing, refer to the lamp matrix and driver board drawing. Figure out the two pins on driver board that light the shoot again lamp. Test across those two points and see if the board is outputing the volts to that matrix circuit. Tell us what you find out...
