Some of you may have read that my MES died today again. Not being one to sit around and just wonder why it quit, I pulled it apart tonight to see what's up. Not much to my surprise, there was quite a bit of moisture built up inside of the control box and around the PCB. I took it out and dried it with a hair drier from all angles for a 15 minutes on low heat, then took it outside a bit ago to test it out. Lo and behold it fired up again for a few minutes before conking out again. The PCB is coated in a white silicon compound of some sort, moisture had creeped in between that and the switches too, so I power dried them direct on for another 5 minutes. This seemed to do the trick, it is now plugged in on my back deck going to work.
Since I already ordered a new controller, I'm going to see one of my genius electrician friends next week at our pinball league and see what he thinks we can do to beef it up out of the box. I think we could easily get rid of the cheap controller casing and overlay and come up with a better moisture proof box and switches.
Here's a pic of it nekkid inside a freezer bag at the moment. I'm seeing how it holds up for the next couple hours with a test smoke.
