...the only bad reviews I just read were from folks who simply went by some bad installation pictures apparently (?) and connected + to one side and - to the other and then wondered why their $$$ batteries went up in smoke (sigh) ...

George Carlin was known to say that the average American was an idiot, which meant that half of them weren't even that smart.

Yet another line of comedic brilliance from said man ... worthy, or at least on-par with our very own Laitch, perhaps? Hoping this may conclude technical content of the thread before usual tangential descension ... most amusing though it often is ..!

Cheers!

Many people think George Carlin was a comedian.  In reality he was a philosopher who examined and exposed the absolute absurdity of the things the rest of us take for granted.

Does anyone happen to know the diameter of the hole in the lug on battery end of factory ground cable - thinking 8mm? I don't have access to the moto currently (otherwise would measure) but would like to order one of these switches ... they seem to be available with a choice of either 8mm or 0.4" (~10mm) lug mounts on the switch studs - would prefer to re-use existing ground cable to one stud on switch (and then add a second cable for the other).

The OEM battery terminals get M6x25. The Odyssey PC680 L-bracket adapters also use M6. What you have is unknown. You can always replace the cable with a larger diameter cable and terminal, and probably should anyway to feed that unicorn called Peace of Mind.

Thanks Laitch - and agreed re upgrading / over-sizing main ground as many problems I've found on other bikes can originate there. In the case of the switch I'm going with 8mm studs in the interest of flexibiity of installation - and for (perhaps Canadian 'brickers only ie amazon.ca rather than .com) this switch in particular - very similar to koapono / Atlarge suggestion earlier :

I ordered these before BrickDad and others posted about the remote disconnect switches.   

But FWIW - from McMaster-Carr:

3855K63 -  Plastic knob w/ M6 x 20mm SS stud
92871A253 - M6 -10mm unthreaded SS spacer

The spacer is used to provide the necessary offset for the knob to clear the transmission casting.   I also used some M6 SS wavy washers on either side of the spacer that I already had from a previous project.
