Quoted from tem92:Upon further troubleshooting, we narrowed the issue down to opto number 5 being bad. If you look at the image attached, it shows a ball in opto 5 when there are no balls in opto's 3 and 4. Two balls are already in the wonkavator and two balls are in the shooter lane, so that leaves only two balls in the trough (but the trough shows three). Opto number 5 is definitely the problem.[quoted image]
Heres a better image.
