287c caterpillar have no lift or tilt at the right joystick. Driver alert is on flashing level 2 ��! Inside. Check the right joystick for power 12v ok good. Place a jumper wire at joystick from white signal and the ground black check at the ecm hardness had less than 5 ohm. Remover the jumper wire check J2-43 ( wire L804-wh) at the hardness had no resistance to none of the other pins on the hardness. Measurement should be greaterthat 5000 ohms. Do u think there short some where in the hardness. I also check the door switch back to the emc hardness and there no resistance.
