Answer
You have breakers in your bike and no fuses. I would test on both sides of the breakers to make sure you have power coming and going. If the breakers are good then you will have to start tracing wires from the breaker to the problem.
the breakers are located either under the seat of under the side panel.
Good luck and happy riding
