Aren't those primary circuits always active to be ready first for use?
I answered in your other thread, but here it is anyway.

No. Unless J3 Pin-1 is shorted to J3 Pin2 and J3 Pin-3 is shorted to J3 Pin-4 (IE: Run/Tow switch is connected and in "RUN" position) the controller's logic power and auxiliary power are shut off.

Unlike other carts, with a PDS the various switches and interlocks are effectively in parallel instead of series. Each is more or less a stand alone circuit.

Think of it as a five input AND Gate.
1. Reed Switch
2. Direction Switch (This is an "OR" input - Either "F" or "R")
3. Pedal Switch
4. Run/Tow Switch
5. Key Switch
All have to be "TRUE" before Controller will activate Solenoid.

IF any one of the five is "False", the solenoid is not energized.
