BMW Motorcycle Voltage Regulators

Buyer's Guide to BMW Motorrad Voltage Regulators

The voltage regulator is directly responsible for keeping the electrical system's voltage levels within a specific range. What does that mean to you? Your battery and other electrical components get the electricity they need, without random spikes that can cause damage.

How Does a BMW Voltage Regulator Work?

The regulator takes the electricity that your alternator generates and converts it from AC power to DC power. It constantly checks the flow of electricity, lowering or increasing as needed to ensure the proper levels are maintained. Finally, the voltage regulator can protect the electrical system from sudden surges or short circuits -- preventing expensive rewiring jobs.

How Do You Spot Voltage Regulator Issues?

When your voltage regulator starts to fail, the battery has to accommodate the resulting demand for juice. That's going to cause the battery to drain that much faster -- which can leave you stranded by the side of the road. If yours starts to go bad, you'll notice right away. Signs of trouble include:

• Dimming headlights
• Poor engine starts
• Uneven engine performance
• A dead battery
• A malfunctioning instrument cluster
• The "Check Engine" or battery level lights come on -- though these are generic warnings that require further investigation to determine the cause
