Having a fit getting my "new to me "  8520 tractor & 1900 air cart to work together.
Is there someone that could give my man a call & answer some of his questions ?  307-254-1614 aboout 8-9am Mountian time.

 It keeps giving 110 code & he's gone through the wiring 4-5x .

 I'd have the local dealer come out, but they know less about air seeders than I.
