I like the terminal strip idea as there is a lot of strain from wires hanging in free space coupled with vibration of the machine in the original design. Surprises me it got out of engineering, let alone production that way. I addressed each of those coils and the white wrap tape just fell off of each as the oil saturation did away with the adhesive bond long ago. After swishing them around in a vat of board cleaner, then 91% isopropyl and allowing to dry, I then installed small shrink tube over the magnet wire to 16AWG wire connection and shrunk it down. This of course offers great rigidity and integrity to the connection. The one coil with broken wires was the sole one needing resoldered of the leads back onto, but only after ensuring it's resistance reading was very close to the other coils at their respective solder joints which is 21.29 ohms at the then current ambient temperature. A slender bead of non conductive adhesive was then placed across the coil winding to keep it from having possibility of becoming loose finally wrapping the coil with silicone adhesive xfmr wrapping tape in a double wrap. I did order a spool of 28AWG magnet wire to rewind any of these should they present problems in the future. Never have worked with piloted hydraulics in the past, but know the theory well and found your guidance most beneficial. It was in no way looked down upon as too elementary.
No worries about talking straight with me. I built a career being neither politically correct, nor giving a rats ass whom liked, or didn't like me. Not meaning arrogance but I was good at what I did, (as I think you are) and always told it the way it was without exception being sometimes quite blunt with azzwipes whom were management. It can be difficult walking into a problem you've been assigned to repair and have to work with stumped normal maintaining technicians whom are simply at a standstill when you don't know what they've been through. Wanting to do something they've already done nearly always garners or brings out a disrepectful attitude, but this I attribute to frustration, or disappointment in oneself. Sometimes you can change the dynamic, the atmosphere, or the conditions, but one always has to work with what they've got whether positive, or negative. The goal is the same; get something operational that is not, and returned to service. I've always entertained fresh, or new ideas as a new perspective is sometimes quite a useful tool in the arsenal.
You've been a true asset in getting this lift to where it is now; and it is appreciated. I plan to rebuild this until it is reliable as it will be very useful to me in the future and I have the equipment to move it when needed. Those diagrams you had attached have given me both an elementary, and thorough understanding of how the controls and wire terminations work which is enough to attain my goal.
Up to you but feel free to PM your email address and I'll put my appreciation into direct compensation for your input.
I will continue to update this thread as I procede along the path and with this boom raising issue sorted, it should pick up the pace.
Thanks,
