Typically 14 to 14.5 volts assuming a fully ( or nearly) charged battery.
Check the battery voltage, bike not running. Start the bike (crank the rpm's up a little), voltage should be a couple of volts more than battery voltage. Check both voltage (running and not running) at battery terminals. Charge voltage isn't all though, if it doesn't stop charging when it should it will boil the battery dry. If you are having this symptom, it's for sure the regulator
Usually 12 Volt
The battery is charged by a generator that runs through a regulator-rectifier. The generator outputs AC voltage and the rectifier converts the voltage to DC. The generator is normally mounted inside the engine on the flywheel.
put a voltmeter on the battery and test voltage, then start the cycle and check again. A battery at rest should be at about 13 volts, with the engine running it will be at 14 or above. to be sure disconnect the positive battery terminal while running, if there is still good volts there, or the engine does not die it is ok.
it recharges the battery automatically, but it will only recharge the battery if the bike is running.
No, a 12 volt 12 amp deep cycle battery will not keep your motorcycle running. A deep cycle battery is one that can survive repeated deep discharge cycles. As the voltage reduces, however, your motorcycle may stop operating correctly, because it is not designed for this type of battery. The proper solution to your problem is to fix the cause of the charging system problem in your bike. Besides, if you check the specifications on the required battery, you will probably discover that it is rated for much more than 12 amps.
yes i do it often Ok, that answer works-- I've also done it on more than one occasion-- but there are some things to consider. I'll try not to get too technical, but a lot of people misunderstand so I want to be complete. First we have to look at lead acid batteries as are used on both cars and motorcycles. When charging, a lead acid battery heats up. If you try to charge it too fast, it will heat up too much and damage the battery. You've probably noticed that a car battery is a lot bigger than a motorcycle battery which means that a car battery can be charged faster than a motorcycle battery. Consequenty, the alternator voltage on your car is probably around 14 volts (the alternator voltage on my pickup is nearly 15 volts while some of my smaller cars are thirteen point something). Both because the battery can't be charged as quickly and because the alternator is much smaller on the motorcycle, the alternator voltage is much lower. How fast the battery charges depends on the amount of current going into it which is directly related to the difference in the battery voltage and the charging circuit voltage. A fully charged car or motorcycle battery is at about 12.6 V. Ok, that's the technical part. Even if you didn't understand what I just said, pay attention to what follows and you'll probably be ok. When your car is running, the electrical system is operating at a higher voltage to keep the battery charged. The electronics in your car is designed to handle the higher voltage. Electronics in your motorcycle may or may not be able to handle this higher voltage. When you jump start a motorcycle from a car, make sure the car isn't running to avoid damage to the electronics on your motorcycle. Older or more basic motorcycles may be ok because they don't have much in the way of electronics but on newer motorcycles-- especially if you have fuel injection or electronic ignition-- serious damage can occur if the car is running when you jump start the motorcycle. So, only jump start if you must and always jump start with the host car not running. Trust me on this. You don't need the potential heartache.
12V is the standard rating of a battery designed for the V strom. It's running voltage can go up to 14.6v and can be as low as 10.5v and still be useful. The voltage will vary if, when tested, the engine is running and the regulator/rectifier is trying to charge the battery. The voltage will also vary depending on how many accessories are running at the time of testing.
If both batteries are of the same voltage (12 or 6) yes, you can use the charger. make sure that they are of the same voltage.
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.
Once the engine is running it mechanically turns an alternator. The alternator generates a current which powers the motorcycle and also recharges the battery.When removed from the motorcycle the battery will need to be recharged using a specialist battery charger which plugs into household mains.
All Harley Davidson motorcycles have used a 12 volt battery since 1965. Prior to 1965 they used a 6 volt battery.
