I'll tell you straight up that electrical whatnot makes my head spin. I greatly appreciate the feedback and intel, spudley. The Prima G3 has some weird built in oddities, like the resistor in the brake light assembly that, if you don't have, will kill the engine if a bulb burns out. So it might be that the quirks are more about the bike's wiring than the brake control workings. I do know the Prima G3 takes a N/O (normally open) switch.
From the wiring diagram:
"RH Brake light Switch
Switch is a NO type (normally open ) in it's relaxed state (Position when brake lever is squeezed). When the brake lever is not being squeezed, a ground connection travels thru the switch which grounds out the black w/red wire."
When I put the multimeter on the switch that is currently in there to test for continuity, these are the results:
button up = continuity
button is pressed in = no continuity
So when I pull the brake lever it creates continuity. When I release the lever, no continuity.
I'm a Luddite about electrical so, in an attempt to better understand, I went here:
"We close an electrical contact to start current flow and we open an electrical contact to stop current flow."
Closed = Current flow
Open = No current flow
So I need no flow when the brake lever is pulled (popping up the button) and I need flow when the brake lever is released (pushing the button in). Is this right? And does "continuity" = "flow"?
