Great thread for SW DE. Picked up one myself along with a High speed not too long ago. Stripped the play field, new plastics, LEDs, had the ramp rewelded, fixed a few cooked molex connectors. Overall not in bad shape. Still need a better trans light but not too excited to pay $100. Also needs new coils as I cannot shoot the ramp with the right flipper.

Did run into one problem and I wanted to see if you guys have any thoughts.

Having trouble with the Star Wars letters and 3CPO mouth light. In demo mode the Star Wars letters light appropriately going back and forth but when playing the R always stays lit after I light a letter (see pic). Pulled the PCB were the lights are at, looks great, all the tracts intact, tried new bulbs, new sockets and no luck, even took the old wires out and re did them with new molex connector. Still the mouth won't light and R stays lit. Not sure next step but maybe something with the back box board where they connect? Any advice would be greatly appreciated.

The lamp board looks in great shape, tracts etc. I compared the wiring to another thread with pictures and mine looks exactly like that (i.e colored wires match up on the molex). I even refitted the wires in a new connector to see if that would help. Makes me think it is somewhere down the line.

Have not done this. Will take a look. Would that explain both problems?

So in diagnostics the mouth lights up appropriately. The letters switch back and forth appropriately but unfortunately when playing the R is still dimly lit. Interestingly one of the 10 million arrows also is dimly lit. Maybe something to do with the LEDs?

The work continues on restoring the machine. Thanks to the prior user who suggested that the flickering Star Wars letters were probably ghosting LEDs. Unfortunately it has become a weak flipper problem and I was hoping for some thoughts.

Both flippers are weak but flip freely. I have rebuilt the flippers and changed coils. Game is appropriate level/angle. Everything else works without issue. Have tried both a new rotten dog flipper board and the original flipper board which looked fine but I still ended up picking up a RD board anyway.

Things I have tested so far by tracing the voltage from PPB board to the flipper coils in this order

1. JN4 connector on the PPB gets +50v AC, actually more like 75v per my multimeter
2. JN7 connector on the PPB shows 75v DC
3. CN2-8,9 connectors on the flipper board show 75v DC
4. CN2-6,7 connectors on the flipper board show 9v AC
5. Fuse F2 and F4 on the flipper board (AC fuses) see 9v AC when I press the flipper buttons both left and right
6. Fuse F1 and F3 don't see 50v but it looks like the most I have seen on multiple tests has been maybe 20v (maybe 40ms is too fast for the volt meter to show 50v?)
7. Flipper coils both left and right see the same thing around 20v and hold at 9v. At rest (no flipper button pressed) there is not voltage at the coils.

So it looks like both the appropriate AC and DC voltage is getting to the flipper board but from here its a bit confusing. Should the coil be seeing any voltage when the button is not activated. I have seen in some post that the 50v should be there all the time but is cleary not the case on my game. Is there something here that I am missing because as is, the ball barely makes it up the ramp entrance and sometimes mid ramp at best.
