I'm going to keep this thread a bit generic since I'm sure I'm going to have a bunch of questions as I trudge through this swap, so here we go! I'd like to give the rails in my Flash Gordon swap a fresh coat of paint before installing them. However they were milwaxed several times. 1) Will...

I'm about to endeavor on a PF swap on my old Flash Gordon. It's going to be a long arduous process for sure, but I figure I have at least a month of cure time anyway so I might as well take my time and do it right. As such I want to take this chance to polish all the metal bits. I've read on...

I don't have a system 11 machine to look this up on, but the interconnect schematics seem to show a lot of "Insert" connectors (J11, J13, J17, etc) What are these used for? Are they necessary? I suppose I should start with my assumptions on the schematic, so for the switch matrix lines (top of...

Custom pin I've been sitting on this idea for years, a few beers and digging up ye olde Arduino finally kicked me into gear on it. I had a thread going on vpforums but it seems a bit more relevant here so off we go. The design was originally spread around the bally board set entirely. I ended...

Parting out a machine that's seen one too many quarters? I've got a custom build rolling that's more or less sane at this point, and I need to start looking at playfields instead of torturing my poor FG. I'm looking for playfields in pretty much any condition as long as they are: - Complete...

After weeks of troubleshooting and overall head bashing, I've come abit closer to isolating the problem. In a nutshell: - When the right flipper is pressed, sometimes it will trigger the left pop bumper or slingshot. Happens sometimes on press, sometimes on release, but almost never during the...

Another weird problem which has surfaced on my Bally Flash Gordon When the ball drains, everything scores normally, but right after the kicker returns the ball for the next round, points get added and a sound is triggered, as if a switch was hit. However, the switch test confirms no switches...

When I was rebuilding my rectifier board, I didn't have a desoldering iron with a large enough tip to go after the fuse holders, so I figured they were fine. Surely fuse clips don't go bad! Hah. FG started rebooting randomly today. A few hours with the DMM traced it back to the rectifier...

I was tweaking around on my FG, trying to get the contacts set just right. Halfway through the displays and feature lights all go dead. PANIC. I pull the backglass. MPU led is dead. Panic more. Bust out the DMM. Tp3 is 0v. I lift the PF. F3 is blown. At this point a million "OH CRAP" ideas...

Bally voltage issues: Insanity ensues So, at the moment my Flash Gordon isn't booting. The LED on the MPU is dim,and does not flash. voltage at the MPU is 4.1v (well below the minimum to start booting). The same voltage is found on the A3 solenoid board. Originally it was also blowing F1, so...

Flash Gordon restoration So, on a whim, I went to check out a local ad for a pin "for parts or repair", listed at an absurdly low price. It's now sitting in my apartment, in pieces. Not sure if I should be proud of my find or start crying. I love messing around with electronics, but this is a...
