I would guess you either have a faulty solenoid or you have the positive connected to the wrong side of it. the wiring for the lights and other accessories is usually connected to one side of the solenoid
.Likely your bike sat in storage and the battery went bad or, you put off buying a battery and keep nursing it along. . Then u tried to start it with a weak or bad battery. The start relay gets lazy and sticks due to the weak voltage. So, when you try and connect the battery, the engine cranks by itself. The bike will crank even with the key in your pocket. This is an expensive repair as likely the relay, starter are both fried. There is an update kit from BMW moving the relay out in the open for the next time it happens. Best to use a small float charger like a battery tender to prevent his from happining again.

Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
