The alternator creates alternating currents to run the bike and charge the battery. The regulator/rectifier changes, or rectifies, the alternating current produced by the alternator into direct current so it can be stored in the battery and regulates the amount of current produced to prevent overcharging.
Does idling a motorcycle charge the battery?
Technically, a motorcycle battery does charge while the motorcycle is idling though it does not provide as much amperage as when the motorcycle is at higher speeds. During a normal ride, a motorcycle provides about 13, 14, or 15 amps while idling only provides less than 1 amp.
How do I keep my motorcycle battery from dying?
Keep your battery terminals clean and free of corrosion (a bit of silicone or grease can help), and check them now and then to make sure the fasteners haven’t vibrated loose. If you don’t plan to ride it for an extended period, disconnect the terminals.
Why won’t my motorcycle battery hold a charge?
Check your wiring harness for a short to ground. If your battery isnt holding charge and it isnt too old it is most likely a wiring fault. If it is old, then it is time to get a new one. You could also have a problem with your voltage regulator or stator which is leading to incomplete charging of your battery.
Do motorcycles have alternators?
Do Motorcycles Have Alternators? The simple answer to this question is yes—however very few automotive style external all-in-one alternators exist on motorcycles. Rather, a stator and rectifier/regulator handles the power generation task.
Why do motorcycle batteries die so fast?
All too often, motorcycle batteries die young, murdered by neglect. Dehydration, improper charging, and a slow discharge during storage all shorten a battery’s life. … To prevent these draws from killing your battery, you could disconnect the battery, but even if there is no load on them, batteries self-discharge.
Is it bad to let a motorcycle idle?
You’re better off just letting your motorcycle sit unless you are actually going to ride it for a fair distance. You see, idling your motorcycle in the cold not only wastes fuel, but it’s also stripping oil from critical components that help your engine run, namely the cylinders and pistons.
Can a completely dead motorcycle battery be recharged?
If you do have a dead battery, you can recharge it with a battery charger (this is preferred), or by jumpstarting your bike with another bike or a car. … Once you get the bike running, make sure to ride it for a good while in order to get it fully charged again.
Can a motorcycle run without battery?
On an electric start only bike, the battery is needed to start the engine. After that, it is the alternator that takes over and provides the power. … Some motorcycles will also be able to run, but have no lights at all as a battery (whether dead or not) is needed to complete the circuit for the electrical system.
How long do motorcycle batteries usually last?
Battery manufacturers agree that on average, a motorcycle battery should last 48 months, yet most of us are lucky to get half of that, and in most cases the battery’s premature death can be chalked up to a lack of maintenance.
How do I know if my motorcycle battery is bad?
If your kickstand is up, and the bike won’t fire, this switch may be faulty. Consider, too, that if your headlight comes on and is typically bright, and your horn sounds normal, a dead battery is unlikely. Telltale signs that the problem is the battery include weak or nonfunctioning lights and horn.
How do I know if my bike battery is bad?
There are several symptoms of a dead or dying motorcycle battery, ranging from the ignition not being able to turn and the battery not holding a charge to cracks, bulges, and discoloration appearing on the battery and more.
How often should I charge my motorcycle battery?
Even if the motorcycle is unused, it should be charged within a month, or it can be charged with a smart charger that will not let the battery be overcharged.
Can a motorcycle run without a rectifier?
Without the rectifier and voltage regulator converting the variable voltage AC output of the alternator to a usable 12–14 Volts DC, the battery will not be re-charged or be able to keep up with the demand of the ignition system and any lights or accessories that are switched on.
Can you jump a motorcycle with a car?
Finally, let’s talk jumper cables. This is really no different than jump starting a car. You can jump a motorcycle with another motorcycle or a car. … A large car battery has plenty of energy to fire up a bike within a few seconds, without the need for the engine to be running.
Will a motorcycle start with a bad Rectifier?
The rectifier is part of the charging system. If you put a freshly charged battery in your motorcycle, and you have a bad rectifier, it won’t stop your motorcycle from starting, but your battery wouldn’t stay charged. The regulator/rectifier on your motorcycle performs two functions.
