I am now back in Reno. The very first thing I did when I got here was to take off the covers of the Tesla Wall Connector. I found EVERYTHING to be exactly the same as in Auburn. All wires in the same order, as dip switches set the same, etc.
So I decided to try it with the same Tesla Tap again, with the same bike.
It's now working perfectly! I have no idea why. I did not change anything at all.
I admit to making one mistake and that is I took the Tesla Wall Connector covers off before trying it again here. I should know better. However, there were no pinched wires or anything like that. I kinda assume it would have worked even before I touched it here today.
I am now using it to top off the charge. I am no longer getting that "DC initialization" message or anything like that. So I have no clue why it didn't work at all few days ago, no matter how many times I tried, both at a very low charge on the bike as well has a much higher charge on the bike (I charged up at the Reno HD dealer and then checked the L2 charging at the Western Village Casino in sparks. Both of those worked. Then I came back here and had the exact same problem again, until today.
So now I cannot say for 100% certainly if it's an intermittent problem with my Tesla Wall Connector, Tesla Tap or the bike!
