I bought a 4 row wide 7000 a couple years ago. Narrowed it to 4 row 30. The first year, I found some dirty connectors that I cleaned with DeoxIT, an electronic contact cleaner, and it did fine for a while, then one row alarmed. I cleaned that with a sensor brush and the monitor worked fine. Last year doing beans (with Kinze seed meters) some rows would come and go seemingly at random. I never did catch the seed meters missing seed and the crop was good. This year the middle rows worked fine, on the outside rows the monitor didn't admit seed were falling though when I checked by hand they all were dropping seed and seed was being planted, I found when I dug in the rows. Between planting days I found a loose splice on one of the row wires and fixed that. By then one of the outside rows was detecting seed most of the time. The day of planting after I fixed that loose wire, three rows monitored reliably. The other outside row never admitted seeing any seed. But I manually divvied up that last sack of seed and when I got to the end of the field, all seed hoppers had the same small amount of seed. So I've confidence that all rows planted. Wiring color codes are in JD manual TM-1270. My copy is not handy right now. There may be a copy or two on epay at times, last I looked there was one or two. Its the planter monitor technical manual, not all sellers give the JD number though sometimes you can find it on a picture of the front cover. Gerald J.
