I am trying to figure out if one of the boards on my Joker Poker is causing my machine to not properly boot. I also know that I have one locked on coil(chime unit)when I try to fire it up that I have disabled for troubleshooting purposes. I have a perfectly good working Sinbad(sys1) that I thought would help me determine if one of the boards has an issue. I have already checked the voltages coming to the PCB's on the Joker Poker and they are good.
SO... Which is safer? Check the boards from my JP by putting them in the Sinbad one at a time, or vise versa?

THANK YOU IN ADVANCE FOR ANY HELP YOU CAN PROVIDE!!
