REPAIRED! I opened the shrink wrap
@Joesmoe and I had finished with on Sunday and just like
@DEcosse thought, the liquid tape we used had not cured and all three wires were in contact with each other.
I cleared the now cured liquid tape and found the solders to be strong, thus I did not cut the wires to start over.
I insulated each wire with electrical tape then wrapped them all together.
I rode the bike and saw the speedometer climb as normal and the self canceling blinker function has returned. It took about 3 miles before the gas gauge registered but it is back as well.
Thank you Paul for your time and help with troubleshooting and the learning point about proper curing time on liquid tape. Maybe even to not use it ever again.
And thank you too Ken for diagnosing the road speed indicator as the issue and not the "Red herring" of water intrusion. It may be that the water hit was what finally broke the wires as they are right on the bottom of the engine, but that is just a guess.
It is such a relief not to need dealer intervention!
