Got my T2 up and running but it keeps rebooting itself. It's not instant, sometimes it will run just fine then others it will sit there and reboot 3 or 4 times. Any ideas?
 
That was my first guess. Im getting 5.1v out of the +5. It didn't change at all when it decided to crash. What should I be looking for?

if you can look at voltages on the chips. I bet they will dip a bit at some point causing the issue you have. Check and clean connectors also will not hurt. If it is not a power issue then you have something that is getting ready to fail sometime in the future. Intermittent problems are never much fun to track down.
 
Not something I'm looking forward to.

I am very surprised at how well these games have held up over the 20-30 years they have been around. They were only expected to last 2-5 years. The boards really surprise me at some of the abuse the can handle, wrapped in bubble wrap with Styrofoam peanuts. Power supplies that try to compensate for resistance at the connectors, upping their voltages to compensate (arI, arII, arII). Most cars on the road aren't as old as many of these games.

that's how you do it. cleaning the edge connector is monumentally simple too, you just do it with a pencil eraser. just make sure the little rubber pieces get rubbed away from the board, you don't want them getting stuck anywhere.

chances are also you're rocking the original Peter Chou power supply in there. surprised the game resets and just doesn't outright shut down.
 
I think I got lucky. I pulled the board and made sure everything was seated and pulled all connectors out and plugged them back in, then I noticed two wires from the 1st player gun harness were broken. Got it put back together and it played flawlessly. Somewhere along the line I lost my recoil for the guns, gotta fix that, but considering this is how it looked when I started...

I'm having trouble with my recoil as well. Did your recoil ever fully work? I took my guns apart and I can barely move my solenoids by hand so that is my problem.

If you have a short, or if you solenoids go bad like mine a series of fuses can blow. Four of the fuses are on the coil driver board, below your main board. These fuses control your recoil and your flash bulbs. There are also two additional fuses that are mounted to the bottom side of your control panel. I have the PDF manual that lists the fuse sizes if you need it, just let me know.

epic info here, learn it love it live it

and for the love of god tell your mom to stop using it as a birdcage. (j/k but clean that out lol).

Haha. Actually, she was into rats. It has been scrubbed and repainted since. The recoil was working on both guns, when I had it in pieces. I'll have to check those fuses, I know the bottom fuse on that board was blown before. I never noticed the fuses on the control panel. I'll take a look at that tonight.
 
if it's blowing fuses constantly you need to inspect your connections for shorts and the actual boards for things that shouldn't be touching each other.

or the obvious, is the fuse you're putting in the correct rating?
