THIS IS KINDA TURNING INTO SNOWBALL/AVALANCH ,so after blowing fuse for boom sensor, it would blow after a bounce or two, swapped out sensor on boom with a know good one and fuse blew the same way, checked boom harness found suspect damage to cover so installed new harness, now have these codes 2476-3 2477-3 2474-3 2475-3 458-3 41-4 and park brake won't go off. any ideas, or what am I over looking with either issue, triple checked connectors that were plugged in correctly
In mean while I overlaid old harness back in and problem is still present and looking not seeing anything that I may have knocked loose , still pulling what is left of my hair out
Would you like to start with a machine Serial Number.? I see multiple models of 289D3. A S/N makes it far easier to look up information. Out of that list the 41-4 is a very likely candidate because it relates to the 8v stabilised power supply to all the sensors. The -3 Codes for 2474/75/76/77 all relate to joystick position sensors. 458-3 is the tilt cylinder rod end pressure ensor.
JX909658 I think I deleted original code from the blowing fuse but its not there now
Check your messages for an electrical schematic. Attached the troubleshooting for the four joystick Codes.
