BMW Motorcycle Electrical Systems

Your motorcycle most likely has a battery on board. That's what delivers the juice needed to start the bike. The battery also stores a specific amount of electric energy. It's charged by an alternator -- or generator -- that's drive by the engine.

Most motorcycles also feature a rectifier unit that converts the AC electricity from the generator into the DC electricity that your battery needs. In addition, parts such as your lights and electronics require DC power in order to work properly. Of course, there are also the many switches, wires, and relays that enable the system to fully operate.

How to Spot a Faulty Electrical System

Even the best electrical systems can go bad over time. Signs of this include:

• Lights brighten and dim while you're riding
• Your engine begins to sputter when you're riding
• Your bike won't start
• The battery warning light comes on
