Gentlemen, I congratulate you for your knowledge and wisdom. I may not have followed the procedures in the book precisely, but in spirit and practice. I checked the solenoid first as suggested and it was fine. Then instead of breaking every possible connection along the way (to avoid disturbing otherwise working circuits), I ran my test jumper all the way from the solenoid connector to the transmission controller in a single run. Just red butted for the test. Wrapped the wire safely out of the way and off we go for a test drive. This was wire T06 Blu, and I will label the sub for the next tech.
I drove the thing over an hour and a half, over hill and dale....smooth and rough, uphill and down. I did everything but try to drown it, although we do have ponds and the thought did cross my mind. It never even blinked. In the morning I'll go swap to MTW and solder and shrink the splices and wrap to the existing loom. Then just a couple of access panels and some trim.....all done
Well done, guys....couldn't have done it without you. Help most appreciated. I'm still not green-tagging this machine because of the low brake pressure warning light, so I guess I'll track down the pressure sensor and have a look. I must have pressure, it will throw you thru the windshield, so I'm hopping for a faulty connector, wire, or sensor. If I have to measure the pressure, I hope there is a gauge port. I haven't checked for electrical specs on the sensor, but couldn't check that too. Or just replace it. it's original.
Looking in the electrical cabinet, I can see it's been worked on by a hack, so no wonder there were so many codes. Lots of live wires just cut and laying. Trashy appearance. No telling what really works right and what doesn't. I'll work off the operator "crab sheet" for a start.
My local dealer/service center was not familiar with the Hall Effect FNR switch. Probably mad because I was right he was wrong. He didn't sell a new computer.....which wouldn't have fixed it anyway. Any chance one of you can get me the PN? I can order from Dallas or Houston just about as easy. I think unless it's twice the money the original style is, I'll update it. Will save a headache later, I'm sure.
That's about the end, or near it for this one. Already got another lined up, and I'm sure hoping someone here is a Kobelco fan. I have an excavator 20 miles from the shop (can't recall the model) that won't run. Computer full of codes (sound familiar?) and rodent damage to harness....somewhere. Looked at this one a couple of years ago and one of the codes doesn't exist, per a factory phone call.....oh well, I love a challenge. New harness is north of $10k, so planning to try repairing it. Everyone chickened out on me last time we wanted to use it, but need is more urgent now. Hate working on it where it is, and moving it seems like a project. Boom and Bucket are extended and sitting on the ground, cab is turned about 90°, so there will be some discussion about it and whether I really want to tackle it. But that's all for another thread, and I'll try to get the manufacturer correct this time. I'm really not that dumb
Again, many, many thanks for making me look good!
