OK so I have a Creature that isn't getting power to some of the GI circuits. The lights underneath the slingshots, some connected flasher bulbs on that same yellow circuit and some of the backglass lighting all have no power. Along with seemingly the coin door.

At first I thought I was dealing with a short circuit, but miraculously when I was installing new ramps and replacing some bulbs, the lights came on perfect! Under the slingshots and even in the backglass - seems like all of the GI strings were fine and the machine looked beautiful! Turned the machine off and back on to see what would happen, and the GI circuits were back off, never to be seen again. Most of the GI works fine. I think it was GI circuit 2 and 3 that were out? I blew two fuses when i connected a bulb by jumper cable but I can't remember off the top of my head which ones right now as I'm at work.

On a seemingly unrelated note, I had to reflow some cracked solder points on one of the signs so that the bulbs would stay lit. That got me thinking, maybe there is a similarly damaged connection for those GI strings and I managed to jostle the machine just right for the connectors to touch the solder points but now it's rattled back out.

Long story short, if anybody knows where the connection points are for these particular GI circuits, it would save me some trouble trying to find out myself. And I'm not even certain I'm on the right track. Any advice would be greatly appreciated, along with specifics about where these things are connected.

Thanks mot, that gives me a great starting point.

Ok so lo and behold at all of the connections you mentioned it looks like the board has been resoldered. All of the other pins on the board look good. Take a look at the picture and let me know if it might be something else, but I think I just have to clean up the solder points a bit and make sure they aren't touching.

I scraped away some excess solder from between the pins, I think that might have been causing a short. I can see visible gaps now so hopefully I can go put the board back in and pray. Didn't need to fire up the soldering iron so far, just used a little metal brooch that was lying around. There is some excess glare in the picture from camera flash but the gaps all look dark green, not silver like they appear.

Hm... No change still no lights in the slingshots or power to the coin door. Looking for more ideas

My dmm is still in the package, time to bust it out I guess. As I said before when I had the playfield tilted up to service the machine, everything came on once. So maybe it's a single disconnected wire or something causing this? Maybe because it runs power through the triac board? At any rate I will do some sleuthing tomorrow night and update you on what I find.

Yeah sorry, haven't gotten around to the fix yet, I came down with a cold and have been laid up a couple days. Will update when I get a chance to check it out. Definitely go through the advice posted in the thread so far in the mean time. I would suggest mot's jiggle suggestion first, because if it is a bad solder point you should be able to jiggle the connection and make the lights come on.
