NW Ohio | Does anyone know if there is a fuse or relay in the power cable going to the NAV controller on the T7000 series tractors? Tractor was purchased auto pilot ready and had a NAV controller installed in 2012 or so. It has worked up until the last couple days of planting this year and I am currently getting error #86 "Battery voltage low" or something similar. Only happens when I try engaging auto steer. Checked power cable into TMX and it reads what my tractor is showing me (12.2 volts when off, 13.7 volts when running). Under Diagnostics for Auto Pilot, it shows only 10.2 volts when tractor is not running and, 12.0 volts when the tractor is running. I checked this cable with the Volt Meter and that is what I was getting also. I am assuming it should show the same as the TMX. I was hoping a faulty Relay could cause this but I cannot find one.
Nav controller is powered using the harness that came in the tractor, TMX is powered through different cables. | |
