I opened an old Prestolite box today, and it further confirms my suspicions.
It contains 3 relays and a circuit board without any integrated circuits.
Looks like one relay is for ignition and one is for glow plugs, and one is for general electricals.
Reminds me of the story of the brilliance of Steve Wazniac, who decided to design a computer by consolidating the functions of integrated circuits controlling things like timing. He assigned one timer the job of several used in previous generation computers in order to downsize and simplify...
Current PCB units were redesigned to use only one relay for several functions. Most iterations of PCB's(excluding the KDS Smart Start) use one relay, as a streamlined design, allowing the PC Boards logic center to swap between functions.
Now that I want to re-design a simplified PCB internal bypass, the old 3 relay Prestolite design explains a lot, and makes the 2 relay design in the PCB from the 5 tonne and up Forum makes more sense.
I think a two or three relay pushbutton box that deletes the printed circuit board is within grasp. The Human Being will act as the logic center to press buttons as needed to activate/de-activate functions.
Football and tailgating tomorrow, so the rest of this project may continue after New Years, definitely not before Thanksgiving.
