Hi ...... Is battery 'hot' when/as it runs or boiling (see bubbles) ? Fully charge battery up and using a multimeter take a reading across the battery when engine is running, meter should show 13.2 - 14 volts ......... a lot more than that and your regulator is defective, turn the meter to alternating current and if it shows a reading your rectifier is defective.
Let us know how you get on.

On my 2004 883 Harley, the battery will be dead but can take it out of the holder and it will start and meep running but next tie is dead again. The battery is new.

I am not understanding how it starts with the battery out of the holder. It will keep running without the battery connected if the charging system is providing sufficient voltage and current for the ignition system, yes, because it is not a field excited alternator but a permanent magnet type. If you explain what you mean as above I may be able to advise you further.

Check your battery cells individually. Get a cheap little Fluid eyedropper type tester. If there is one cell that is showing dead, it's a write off, get a new battery. The Yasa battery company can give you the PROPER number codes for your bike. You may have a battery with an under requirement amp hour rating. Some shops just sell you what fits. It still runs because the stater runs the ignition system and my even run your lights fine. If it is a bad battery don't just fling one in and go. get the new battery fully charged with a 2 amp charger and test those cells too. They must be fully charged. Do not just wing it. Battery's have a sort of memory. Once you begin to use that battery, it will only ever charge to the point it 'remembers'. you need a strong battery to turn over a Harley. Fill the new battery , charge it then level up the acid to the marks. Can't see the marks cause it's a black one? Put a Maglight or other strong flashlight against & behind it and you'll see the acid level. All else fails, visually make sure each cell has acid over the lead plates.

The battery is not charging in riding time . Battery new fitted after 300 kms Battery become dead what is the solution for this problem ?

Check the charging voltage at the battery with the engine running, it should be about 14 volts if you have a 12 volt system or 7 if you have a 6 volt system. The voltage should be about 20% above the normal battery voltage with the engine running at about twice the idle speed, to charge it.

I got a 2008 cbr 600 rr I put 3 new battery on it and they keep going dead they are kinda cheap battery my bike will run abt 2 hour on a new battery then it goes dead and wont push start and it makes a...

Put a charger on the battery for two or three hours. Now start the bike up and use a voltmeter to measure the voltage across the two battery terminals while the engine is running around 2000 rpm. The meter should read around 14 volts. If not, the charging system needs to be checked. If the charging system is working properly then yes, something is draining the battery. You will need to check all the wiring and switches to locate the source.

I have a 2008 MS3 250 that will not charge

The battery may be dead and won't receive a charge. If you haven't already, try changing the battery, but charge the new battery on a battery charger before you put it in. You don't want the charging system to have to start off trying to charge another partially charged battery.

I have a 1988huricane 600 with a charging system

Charging fault as the running engine will produce current if magneto / alterantor is working. Check charge rate with multimeter across battery terminals = 13.8v - 14.5v at just above idle. Some are up to 16.5V at 5000rpm, but you will need to check against your manul.

2006 Bonneville America electrical failure

To start with, your battery was probably already low. You have to be at about 4000 rpm for the charging system to kick in and put out 14v or so. So if you just sit and idle, you will eventually run the battery down. If it is already low, you may have run it down below where there are enough amps to start it again. I know my 2002 BA started having what appears to be charging or regulating problems and the batteries won't stay charged. Try charging the battery with a good trickle charger to begin with. Then, when it is fully charged, run the bike and see if the charging system is keeping things up.

I want to know,tunning of rd350 engine.wat will be gap between points. because my bike,doesnt start properly,missing the spark.problem with carbon in points

Put a fingernail file between the point contacts then press the contact arm down lightly as you move the file in and out. Filing the points gives a new surface to pitted contacts. The standard gap is .015. I assume you have a timing light to set the timing. For parts, try the link below.

My motorcycle battery is not holding charge

If it's not holding a charge I need to know when it is loosing it... By this I mean is it running and not charging or is it going dead over night ,week , month? If it is going dead when you are running the bike I would say it's not charging and need to check output of the stator. If that is good next logical place is regulator rectifier. This is a common problem. If it is going dead when setting you will have to find a short circuit, you can start by using an ampmeter and disconnecting the ground cable to put the ampmeter in the middle, start pulling fuses till amp load drops and that will be the circuit to start with.

08 650 executive, new battery but charging system doesn't charge

Your running off the battery until it dies. Check your chargng system. It should put out 13.0-14.5 volts. If not then the current will flow from what ever source has the most voltage. Thus, your dead battery. Try changing he voltage regulator and then check the stator next. Sometime stators can have burned section on them and reduce the voltage produced to the battery. Also check for really good connectin to the terminals. This can rob current and voltage by upt o 40%.
