The bike: 2014 RT.
The issue: ABS, ASC, battery, red triangle lights are lit. Turn signals, fuel gauge, and sat/nat inoperative.
The story: Left a USB/volt meter in the canbus socket for a month and when I went to start it, it was completely dead. I tried to charge the battery with a canbus Optimate but the lights and dash flashed and the exhaust valve and some other solenoid just click and buzz. So I put a 2 amp charger directly to the battery. It took a charge and started the bike. When I rode it, the above issues became apparent. I thought maybe the 7 year old battery was N/G and replaced it with a Yuasa. The bike started and rides fine but still the above issues. So I did a hard reset. Started the bike and still the above issues.
WTF is going on?

Re: Issues after dead battery
You may need to read the error codes and see if there is anything registered in the ecu
It may also require a reset with a diagnostic tool
