Gottleib.
This game was going to be a litmus test for me. I have only been into pinball repair for a relatively few years. And only more recently in Solid State. (Since then I've pretty much given up on EMs). I've worked on early Bally and Stern (same thing, really). Williams system 6 through 11. On all these, there is copious amounts of information available online. Clay's guides. IPDB. Pinside. Every problem I've ever come across in a Williams SS machine, someone else before me has already had that problem, figured it out, and posted the solution online.
Gottlieb Solid State. Not so much.
My personal experience with Gottlieb Solid State was trying to fix a Dragon for a customer. It has a squirrely problem that I spent quite a long time trying to figure out. After many hours of research and repairing, I had finally diagnosed it had a bad spider chip. Game Over. Ni-Wumpf!

For me, that was a Fail. The customer didn't want to spend the money on a new board. And I put in a lot of time an effort that I didn't get paid. Lesson learned. It really didn't do much for my confidence, though.
I heard that Clay had written up a nifty guide dedicated to this era of Gottlieb. No longer available on his site. Did they encroach on Gottlieb's intellectual property, or was there some other reason? Not sure. How about the IPDB? No Gottlieb manuals there. Sure, there is Pinside, and some other people I can ask, but I like to try to research before asking around.
So, I've taken care of all my non-Gottlieb projects before tackling this. At the same time, my Gottliebs are starting to pile up. I have a Black Hole that I really want up and running, and a The Games on the way. I gotta learn this stuff! I can't call myself a pinball repair guy until I do. And yet, when I look under the hood on this Genesis, I think: Yikes!
Anyway, I decide I'm going to throw caution to the wind, and turn it on. I figure I'll plug it in, then flip the switch. If it makes any kind of strange sounds / smells, or otherwise seems about to burst into flames, I can quickly shut it off. So, I plug it in. It makes a few clicking sounds. I hadn't turned it on yet, so I didn't think much of it. I stand up and walk around the power switch, and see some of the feature lights blinking on the playfield. Now I realize it was on when I plugged it in. Crap, I didn't mean to do that. Luckily, it seems to be in attract mode without any issues.

The funny thing is on the entire playfield, there are 4 working lights. One GI bulb under the right sling, and 3 feature lights. The rest are out. Either every other bulb is burned out, or there is some other common issue.
