Your bike is rigid mounted so the entire frame is a ground. I would simply verify module grounds if you think one is missing. Maybe someone hacked it up and combined the module and lighting ground on one wire and you are missing where they spliced it?

 

Ed:
I found the problem, and is in the worst place.
Is is two ground wires. Not one but two !

They are on a Motor mount bolt, which is also a stud for grounding.

Next to the seat down tube and between the the Primary case.

Oil drain tubes are there. Just save a lot of grief, going to remove the oil tank.

Looks like there was just enough vibration to work harden / fatigue the eyelets Good thing my Zoloft works just fine.

Again thank you for helping and the open mind offering's .

That link that I posted was just what it took for me to look there.

It would explain the eradicate idle. With everything back feeding thru the 16 ga wire at the module.. It is a wonder that is did not burn.

Do you ever go to bike week in Daytona ? I live in New Smyrna Beach Fl, just down the Beach

All better.

Looking at the broken edges of ground the eyelets, they were cracking for a while.
More then likely one had been broke for a while. This problem showed up after the second eyelet failed
Some how the Signal Module survived, yepe !

Again let me thank everyone who replied in order to solve this.
