What charges the battery on a Harley?
The charging system consists of three main components: the battery, alternator, and the regulator/rectifier. Your motorcycle battery stores electrical energy for use and acts as a buffer for the bike’s electrical system. The alternator creates alternating currents to run the bike and charge the battery.
What part of the engine that charges the battery?
The battery is charged by an alternator on modern cars, or by a dynamo on earlier ones. Both are types of generator, and are driven by a belt from the engine. The alternator consists of a stator – a stationary set of wire coil windings, inside which a rotor revolves.
Why is my Harley not charging the battery?
Harley Charging System Failures: Stator Failure: If the stator fails, your battery will no longer be charging when you’re riding your motorcycle. This is a problem because it all loops back to the regulator through your battery negative connection.
How long do Harley batteries last?
Battery Life and Replacement: While the ultimate life of a motorcycle battery is determined by many factors, according to Harley-Davidson a well-maintained battery should deliver at least five years of service.
What are the signs of a bad stator?
The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.
How important is the charging system to the vehicle?
Your vehicle’s charging system has two essential functions. It generates pressure, also known as voltage, and electrical power to run the vehicle’s electrical systems while the engine is running. It also generates electrical current flow, known as amperage, to recharge and maintain the charge in the battery.
Does revving the engine charge the battery?
But when your engine turns faster, the engine’s alternator also turns faster. That way, all of the alternator’s power can be directed to recharging the battery. Once the car starts, you can rev it up to charge the battery faster, but the best way to do that is to just drive it.
What happens when a voltage regulator goes bad?
A damaged or failed voltage regulator can rapidly diminish the alternator’s ability to cycle power from the battery. This may cause the vehicle to experience dimming or pulsating external systems, such as headlights and dashboard elements.
What causes a voltage regulator to go bad?
They usually fail because they’re under rated for the constant current draw. Running the motor with the battery disconnected – or even a poor contact on the battery terminals – can also blow them.
How do I know if my regulator rectifier is bad?
Key Signs to Look For You won’t have any trouble diagnosing the faulty regulator rectifier if the battery is the cause. You’ll note signs right away like poor starts, fluctuating meter readings, and dimmed headlights. around 13 volts, the bike will start to drain the battery.
What causes a stator to go bad?
To answer why stators fail, it is because the coating on the windings breaks down, usually because of heat, causing a short which can also burn the fine wire of the winding in two at the short causing an open circuit. The way to prevent failures is to prevent the heat.
Can a Harley run without a battery?
So, can your motorcycle run without a battery? Most modern motorcycles cannot run without a battery. If the battery is at marginal health and some life is still left in it, motorcycle can be started with a push/bump start.
What are the symptoms of a bad voltage regulator on a motorcycle?
Symptoms of a bad motorcycle charging system
- Motorcycle won’t start. This one’s the big, obvious one.
- Spluttering as you drive. When voltage is low, it’s hard to keep the motorcycle running.
- Lights light up and dim as you rev.
- Battery warning light comes on.
How do you test a voltage regulator?
The best way to test a voltage regulator is with a multimeter, and what you do is you put your multimeter clamps directly on the battery terminals. Positive read to positive and black to negative. And you said it to voltage, and with the car off, you should have a little over 12 volts. That’s that’s a healthy battery.
