I would the suggest the following: Instead of trying to install such a monitor with all of the extra wiring that is needed for that kind of system, I think the best cleaning systems that reduces tailing is the AirJet Chaffer. Because if you are trying to monitor tailings you have the bottom sieve getting filled up with grain and the trash just pushes your grain thru the tailings over and over. With the AJ you increase the fan speed and do the cleaning a lot sooner and allow the unthreshed pods only to go thru the return again. Just my thoughts on the AJ. Jack
