Having trouble maintaining 2500 RPM when harvesting. Keep getting the 1347 warning. Put on new filters, cleaned sediment. When havesting 100 bpa corn, only can go ~4 mph. You go faster, the RPM drops down to 2250. Any suggestions?

Black smoke when the code comes on? if so try replacing the suction control valve. They stick and can't meter enough fuel into the rail. Part number: RE534109

9570 still loosing power

yes had black smoke. Replaced the Suction control valve today, and initially work great. My son took over running the combine and he said that it started loosing power intermittantly. Prior to putting on the new SCV, I swung the auger out, started unloading, and got the 1347 code. Wandering if it is wiring, relay, computor, etc. Any idea's? Does anyone have a wiring diagram for this machine?

Found out today from Deere to replace the high pressure relief on the rail when you replace the suction control valve. When the scv sticks if pops off the relief. With each pop of the relief it looses 5000 psi of relief pressure.
