Thanks kindly and I agree. I was able to get a few things addressed and sorted over a couple of hours this morning. I did get the basket completely operational by cleaning some ground connections, and figuring out this unit needs solenoid coils on the proportioning valves. After verfying the command voltage was being applied correctly, I took after it drilling down to finding one of the leads broke at the coil itself and hanging in free space. These have been monkeyed with in the past as there is barely any encapsulation material on the magnet wire these are wound with at the entry point of the housing. There is absolutely no strain relief anyplace supporting the wire harness to the proportioning valves and this coupled with very brittle wiring makes for the issues I'm finding.
Another issue I found was the latching relay plugged into the incorrect socket. It should have been on the left but was second from left. Only that left socket is wired for the reset command on pin 5 where the others are not.
I'm going to investigate all six replacement coils and get that lift cylinder into a rebuild shop this next week. It really has taken to puking when raising or lowering the boom. Far too much to let it go.
So far electrically it appears to be falling into line with expectations. I'll stay with it as want it to be right and do have a bit of room to spend getting it "up to snuf".
You wouldn't have any other pertinent information on these either electrically, or mechanically would you? I continue to learn, but don't want to reinvent the wheel.
Thanks,
