If someone has one of these can you answer me this, Does it have a big fan in the backbox? I'm not a DMD era collector, I got this in trade. I mean there is a big computer style fan, blowing air INTO the backbox, not exhausting. Seems pretty loud. I've worked on a lot of games but I've never seen (or heard) a fan like this in the BB. It struggles with the attract mode and when a game was played. I was working in the backbox all day in it and I pulled the plug since it wasn't helping anyway. The game ran far better without it btw.
I'm just curious if someone added this in because it sure as hell looks like it was.

I have to get another one then. That is crazy, it doesn't even fit the hole! They must've had a problem with these because there is no way an engineer jammed that big fan over a small hole. The fan seems to struggle when the lights are flashing, or when anything draws power. I think a smaller fan would do the trick.
Are you familiar with the game, I have a few small problems and don't have an schematics. I'd appreciate any help.

I'm just having a slight GI issue with the lower lights on the BG. It's weird. The game has been dead for a good while apparently. Got it this morning still in shrink wrap from a guys garage, dead. Pulled the PCB and reflowed all the pins, cleaned up someone else's crappy work. Surprisingly it fired right up. Broken wires here and there. Was resetting like it had a bad bridge, but I found a broken diode on a pop bumper and just resoldered it. No reset problems since.
Was hoping someone had the GI issue already before I start tracing wires. Would've been cool to wrap almost everything up in one day! I'm also having an issue with the left ramp going up and down, but I see it's been discussed on here before.
