My Doctor Who machine had been plagued, for the past few months, with the awful WPC reset bug and I was terrified that I'd have to do some component desoldering on the driver board (I've lifted many a trace in my past).
Soooo, I went onto the PinWiki WPC page, found the MASSIVE listing regarding the infamous reset issues and started going down the checklist.
115VAC, check.
Good connections to the power supply, check.
Thermistor... hmm....
That's where it got me. The game would reset only within the first few minutes of turning it on. 30 minutes later it would be fine.
Thermistor... hmm...
"Jump the thermistor with a heavy gauge wire," it says. "If the resets stop than your thermistor has failed," it says....
Jump jump jump... turn on... play game....
No resets! Hot diggety damn!
These resources, and these message boards, shit, I don't know what I'd do without all of this. Probably not have pinball machines.
I'm really stoked right now.
