Southwest ND | I have a cousin with a 3400 that acted up while seeding. The controller won't hold the rate on auto. It bounces up and down wildly from say 40-200 lbs product. On manual it works properly. He sent in the controller, servo valve, and flow meter to Micro-Trak and all test out OK buy still acts the same. Controller is getting the right MPH from Trak-Star (?). If it works on manual the wiring should be OK, right? We can't think of what to do next. TIA | |
