My best guess from what you have is that the contactor is partially welded. With the bike turned off, can you use a multimeter to measure DC voltage on the two large pins on the anderson connector? If you get anything other than 0(with the bike keyed off and after maybe 20min or so since last key on), then your contactor is defective and needs to be replaced.
Voltage at the Anderson connector (and the controller) measures 0 when the bike is off.
If you had the proper connector, you could connect to the BMS and get the eventlog from that. That usually should tell you why the BMS is setting BMS 0 Internal Disable, but based on the other things I'm guessing it's the Contactor Welded message.
I'll make a cable for the BMS, but I may make it to the dealer before then.
One thing that stands out to my non-professional eyes is the variable output of the battery voltage.
106.295V from `show bms`
107.515V from start up
And all of these at the `Unexpected contactor close.` messages:
45875 mV 
82812 mV
81375 mV
80000 mV
83875 mV
Yes, thanks for the input, not certain what that's all about.
Today I decided to disconnect the entire harness and removed the pack from the bike (it requires some serious cleaning - dirt, grease, coffee, donuts, etc.) Thankful I have an electric hoist, it made dropping the battery (see photo) a fairly easy task. I did another visual inspection on the BMS and also inside the doghouse (see photo). There's a Gigavac contactor and a 300amp DC fuse. I didn't poke around much but did attempt to measure voltage on what I thought was the contactor voltage out side, with no success. I sealed everything back up, cleaned the battery casing and was going to call it a day, when I tried one more thing.
Wondering how someone would charge a pack off the bike I rolled the battery close and reattached the harness to everything but the motor controller (all exposed ends taped off) and plugged it in via the killawatt meter. Could have sworn I heard the contactor close and wattage was measuring higher than before (35, 45, 54, 42 watts). Voltage measured at the Anderson and controller B+ B- cables were 107.6 to 107.7.
I began smelling something and quickly pulled the plug (with no controller connected voltage dropped immediately). Turns out my neighbor was cooking (more like burning) dinner. Freaked me out!
Plugged it back in but this time the contactor didn't click, so I called it a day.
