Not necessarily. There needs to be a lot more info to come to any conclusion.

What bike? Points, or electronic? What ignition? How many coils? How much juice? How many ignition interlocks? Yada yada yada...

You can have full power to the coil positive terminal, but it will not work if the ground terminal wire does not fully complete the circuit. Check your ground connector resistance (against the engine case metal). If it shows anything other than near 0 ohms, you have a ground problem.

This is what I do for fun, not for work. It is art, with a little engineering thrown in.
