Hi All,

I tore down the top of my #SMDM playfield in order to clean everything, and also learn how to do it, since it's my first pin. Here's the issue: the pop bumpers had bayonet lamp sockets in them, and and all three were not soldered to anything. Needless to say, the lights never worked, and in fact, I didn't even know there were lights in there until I took it apart! So I replaced the bayonets with wedge sockets and 555 lamps, and now I have no idea where to solder the sockets' wires to.

Can anyone help me with this? Maybe take some high-res photos of the underside of the pop bumpers? The one pic on ipdb.org is so low-res that I can't see what's going on.

Thanks!

Check your manual and see if they are controlled lamps (see LDB schematic). They are probably GI though. They are probably soldered to a bare stranded wire held by staples. Can you post a pic of that area?

I have a picture of that area from when I owned one. Let me clean it up and i'll post it in a few minutes. They are GI.

The green circles are around where the pop bumper lamps are tied into the GI circuit.

Thanks for the quick replies! I think I see where they go now. I'm attaching pics of the area, one higher up overview, and a few that show where I think the old leads used to be, which is where I will solder the new ones.
