10. Dead/Weak Battery

Battery and Tester

We’ll get the most obvious one out of the way first. The usual signs of a dead battery are extremely dim running lights that dim even more or go out completely when you thumb the starter. A battery that will no longer hold a charge is characterized by an inability to crank the starter for more than an instant. If your bike starts, lucky you. If not, well there’s always jumper cables. The other sign of a dead battery is the Click of Death. There’s just enough energy left in the cells to trigger the starter solenoid to send out a distress signal: dot dot dot, dash dash dash, dot dot dot.
