Hey, yall. Im new here, but have used this forum before to help figure some things out. However, my current problem is one i havent really seen to much info on. I am working on a 2006 komatsu pc 120-6. SN# 47813. The hydraulic thumb is not working currently. Apparently, its been worked on a few times and it will work for a bit and then stop working. I have ran a new wire and replaced both coils, but now as soon as i energize the hot side of the circuit, everything gets energized even the common and the two switched wires. Any ideas anyone?
