I've Been having a strange issue on my idol Opto in my Ripleys when the right ramp diverter coil fires it triggers the idol Opto. At first I thought it may be the right ramp switch but the problem does not happen when ball lock is activated and only seems to trip the Opto when the diverter coil fires. I just picked up this Ripleys it is home use only with only 88 plays ever so I doubt that the optos themselves are getting weak. I have tried reseating the connectors on the Opto amp boards and on the mpu and cleaned the optos and the window between them. The idol Opto does not do any other false triggers only happens when that specific coil fires any other ideas? My next step is to try to reflow the header pins on the Opto amp boards and see if that helps
