I should also mention that I contacted Jim and he was more than willing to help me but every time I thought I had it fixed so I never bothered calling. He's a good guy, there just seems to be different quirks as the boards work with different machines. I have had 2 WPC89 rottendog power drivers in my BOP and the same thing happens with both, the lights dont work properly and the resistors burn up. In my funhouse I have resetting issues so I abandoned using the boards in that. I actually have a hacked up RD in my TZ now because there seems to be no issues and the hacked up parts are the flipper circuit which TZ doesnt use anyway. The other RD board is in a box waiting for a machine to crap out.
