New Holland BR7060

Very frustrated!!!! Bought a 2013 BR7060 baler and have had nothing but problems. Only 2700 bales. Keep running baler and computer wont grow. Have to reset the bale sensor, calibrate and it will bale about 10 bales and acts up again. Dealer put new sensor on and still having same problem. Dealer said if don't fix may need new wiring harness from tractor to baler which is very expensive just to test with no guarantee. When unhook wiring harness and back in goes error full bale. Any suggestions. So frustrated
