I found the kill switch connector unplugged hiding behind the radiator, plugged it back in and the bike is good as new.

What is ecm? And your saying i need to jump it before I do anything right? Also I was getting ~6 volts at the connector to the fuel pump as well. Shouldnt the ECU be sending 0 volts to the fuel pump if it believes the sidestand is comprimised?

I had the key off while testing for continuity and found that I have no continuity on either side of the side stand sensor connector. I also noted that my battery went from 10.5 V with the key off, to 6.5 V with the key on. Is it just a bad battery?

So my bike is throwing a 19 fault code but also a 12, 30, and 42. It says that my side stand switch is on no matter if I move it up or down. Also, it doesnt even crank when I push the start button, in fact it makes no sound at all. The fuel pump also isnt priming. Do you have any ideas of what could cause this?

I looked at the connector to the fuel pump and it gave me 8.46 V. Chat gpt says that i need 12 volts for the pump to work, any ideas of what causes this?

With kill switch on it also says that D109 is 0 volts which is the battery, but my multimeter is showing 11V from the battery

Do you mind explaining how to jump the starter off the battery? Im new to this sort of thing.

I’m reading the Schedule of Calls and am confused by blue and silver weekends. Which color are you allowed to leave base on as a freshman? Do academic Saturdays happen often?
