Can anyone help in confirming what supplies the 12V to the coin door on TRON? Cleverlyj and I were discussing it, and I know it's an orange wire with red stripes, and I thought it came directly from the linear PS, but cleverlyj seems to think the wire goes to the coin door directly from the power brick instead.

Can anyone shed some... uh.... light? :D www.instantrimshot.com I'll be here all week. Try the veal.
 
According to the schematics....the juice comes off the power supply board...connector J5...pins 11 and 14.

Thank you for the input, guys. I read the schematic but I'm no pro in this hobby so I was having some trouble with it. I guess the link with the sound board helps explain what was happening with it the other night when I was troubleshooting it. For whatever reason, if I twisted the part of the harness by the coin door that connects the coin door harness to the other part (basically the joint where the 2 molex connectors are), sometimes the lights would come on- and when they did, I'd hear some hum in the speakers over the sound that I did not hear before the lights came on. I'm wondering if there's a broken wire in the part of the harness that goes from the sound board to the coin door?

And yes, the J5 connector on the power supply board is the one that has the orange wire with the red stripes on it. If I remember without having the game in front of me at the moment, it's the 15-pin connector. I checked the voltage there on that wire, and it was only reading 9.8 volts, and I'm pretty sure that one's supposed to be pushing 12V out. So, I'm not sure if it's the lack of voltage that's making the lights not come on, or if it's something in the harness near the coin door. Any suggestions at this point would be greatly appreciated.

Bad caps on the power supply could drag down the voltage....a weak connector will also cause voltage loss.

Check the wires right at the coin door lights. If one has broken off and is shorting to the coin door, you'll get a horrible hum in the sound, and you'll start losing a lot of sound fuses.

I'm pretty sure the coin door lights and sound board in Tron both run of AC - so no capacitors in the power supply. It's just a fused line coming from the transformer, IIRC. I don't have the schematics handy to check.

EDIT: I just found the schematics. It is DC - my bad. Unregulated DC, filtered only by C101 (4700uf) in the power supply. In any event, if the sound works properly, I'd focus more on the coin door sockets/wiring itself.

Thanks I will definitely take another gander. These lights WILL light again!!! Mark my words, even if I have to wire up an extension cord and 2 night lights in there!!! :(
