I don't know if maybe mine is just flawed somehow, but every so often when I open the backbox the cover that goes over the siren motor falls off. It's pretty heavy and I feel like it can do some serious damage if it hits the wrong component. It surprises me everytime it happens. It seems to me like it just slides over the motor and sticks there, but there isn't any sort of latch or connection to hold it in place. Today I had the back glass sitting on the pinball machine while I looked at a chip type in there and this thing landed on the back glass. If the back glass wasn't there it would have landed on the pinball machine glass. There was no damage done, but I think it's just a matter of time if this thing keeps falling off. Any tips here on this? Has anyone else experienced this on any other siren game?

Good idea with the tape. Yes that's the thing. I just left it off. Maybe ill try and rig it back up somehow.
