Update: Fixed the fuel gauge issue...all I had to do was unplug the battery.
....also let it warm up again and tried to duplicate the dying issue. After trying for maybe 3-4 min of revving to almost 10k and snapping it off i couldnt get it to do it again....whatever.
My neighbors now absolutely hate me lol.
New issue has come to my attention though function checking everything else, the blinkers and tail light are jack up. When its in its normal (not supposed to be on mode) both front indicators are lit up and the rear ones are not. When I hit the left indicator, the left front turns off and the right stays lit and nothing happens to either rear indicator. The same happens when I turn on the right indicator except opposite. When I go to cancel the indicators, both of them illuminate.
Next issue: my tail light comes on like normal, however when either the rear brake or the front brake are pressed, no brake light and the tail lights stays illuminated like normal. The license plate light works just fines.
Final issue, which isnt a huge issue but might give a clue to the others. Horn no longer works.
All of these issues are the same whether the bike is running or just turned "on". I was wondering if anyone, tripage shoutout to you haha, had a good starting point as I dive into the wiring diagrams of the service manual. Its damn aggravating that these little issues are keeping me from getting this thing fully back together but it comes with the territory...
