I just acquired a RG and everything is working fine except the wheel. When I got the machine home, the wheel was detached and seeing no real way to determine orientation, I just placed it on with the notch pointing up. After a few plays I quickly determined that it wasn’t reading colors correctly. I went into the wheel test and the wheel spins and am getting a 08err with a flashing “h” on the display. I let it run through multiplies cycles which never seems to end. At one point the display read 08err and 256 on the far right. Also noticed that during the test, the wheel seems to come loose and I have to push it back onto the motor shaft. Not knowing anything about this machine, I’m at a loss. Any help is appreciated.
