Hi
I'm a novice compared to many, but got a fair head on my shoulders IMHO anyway, but I do have a question if you could help please.
I'm working on a mod for my car which involved some circuitry, which works & designed etc, but I was wondering this.
Ok I notice they use a ground to signal some circuits, but also I notice the same circuit also uses a ground routed through a resistor obviously for a 2nd signal on same wire which cuts down on multiple wires, can someone advise what the ground through resistor achieves please, as in surely a ground is a ground???
Thanks in advance.
