Update: eliminated one of the copper strips.
There is a split of opinion on my invention, which served me fairly well for 25 years, but the wires soldered to the copper strip would occasionally come loose, which could cause short circuits and other problems. Incidentally, if I did a better job soldering, my invention would have worked better.
The hot wires for the left Z4000 throttle that were connected to one of the copper strips, are now connected using fork lugs (both crimped and soldered to the end of the wire) to the red (hot) row on an MTH Terminal block. It is much less likely that any of those wires will ever disconnect. That left Z4000 throttle powers my inner main loop.
Everything else is wired as before.
As a test, I ran a conventional engine, and it ran fine. Then, I ran an MTH Proto 2 engine using DCS, and it ran fine.
About 25% of this re-wiring project is done.
Will give further updates as I make further progress.
All of your input and advice has been very helpful, and I thank you all for it. Arnold
