Quoted from sacredgaming:A quick update. I have not had the opportunity to fully check the machine. Upon initial investigation the pop bunpers, sling shots and flippers dont work. Alot of the other kickouts work. Hoping they are all tied to one thing. On a side note Even though the GI fuse is blown, i don't see any sections of lights not working.
Will do more investigation tomorrow.
Flipper fuse is on the 50V board. The fuse you pointed to is General Illumination, the lights that come on when the machine is powered up, but are NOT controlled by the logic of the machine. the GI lamps could be playfield, backbox, or coin door. A usual hack made to machines is to jump one GI line to another somewhere else in the machine as one fails (then that line overheats and fails, rinse, repeat). Thus why the suggestion to fix the GI connectors, and check things out.
Special Solenoid 1 is for the left gate ball save, it probably got shorted out and took out its transistors and the fuse for the 6 special solenoids as well (pop bumpers and kickbacks). It also could of fried since the board you have is out of a High Speed (I'll let you figure out how I know) and is a system 11 and you have a system 11A machine. When Williams moved to system 11A they put the damping diodes for the special solenoids on the circuit board, thus you are probably missing them, and this will blow the transistors too.
Replace both the 2n4401 and the tip102 (Q74 and Q75) when you replace them (they go out in pairs).
Then make sure that on the back side of that board someone added the 6 1n5243 diodes to the special solenoid inputs and someone ran a ground wire from 1J18 pins 6,7 to ground, otherwise the special solenoids will not work; the 6 diodes and the ground strap allow the system 11 board to work in all system 11 machines (11, 11a, 11b, 11c).
