  Harley 2015 FXDL - potentially electrical issue? Day running light stopped working. I disconnected the battery and checked fuses. Everything seemed to be okay, however after I plugged everything back in and connected the battery. I had two codes show up. See pictures attached below. The stock headlight has been replaced so there is now a running light that works. The speedometer was bouncing and not reading speed accurately after I reconnected the battery. Exhaust was changed and threw the code P0154 (rear 02 sensor - which will be replaced). Additionally, I have checked and charged the battery (voltage read 12.53). I would appreciate any advice to remedy this potential electrical gremlin(s).
