If your Charging system isn't working properly it won't. Take a Multi Meter. Take the Leads to your battery. Start the Bike and run it up to 2k or higher rpm. The Voltage should increase the higher your rpms get. Up to 14vdc or about. If it doesn't go up then something in your charging system is acting up. Stator, Regulator something of that nature

Hi again just got a new battery, battery light is still on car is starting, but now whats the problem

The BATTERY light indicates that your battery is not getting charged. There could be several reasons for this most probably your alternator, which generates the current to charge the battery when the engine is running. If the new battery is not getting charged, it will eventually drain not start your car. To confirm that the battery is not getting charged and that is the reason for the BATTERY light, put a volt meter across the battery while the engine is running. It should read around 13 volts indicating that current is flowing into the battery. If it reads 11 volts or less, that means the batter is being drained and not charged. Then have your alternator checked.G

Shuts off while drivingi have a 2006 xlt 4x4 4.0l and i was backing in and it just shut off, and i tried restarting it at first it was fine cranked over but wouldn't start, not it won't even crank over. I...

I have seen this problem on v-8 engines but not on the v-6 and the defect I saw was not the result of a gear change. The defect I witnessed would disconnect the charging system even at 70 MPH and if you did not notice it, the battery would eventually run down until the engine quit. The battery saver feature is made to prevent a large drain from running down your battery. This happens several ways. If the charging circuit is working too hard it is identified as a drain and disconnected. You need to charge the battery independent of the vehicle and then try to return the vehicle to service. Or check to see if the battery is bad.

In short, today's charging system is not the same as in the old days where once your engine starts you can fully recharge a discharged battery. (Like after a jump start). The alternators are not made to recharge a battery from a 10% charge or they can overheat. I witnessed a low battery start to charge after a jump start and it automatically disconnected within 5 minutes of the engine running. This gave the owner no other option but to charge or replace the battery.

Hi, i have a honda cbr rr 600 2003, the bike will fire up but it seems while running the battery is been drained flat, when the bike is stoped it will not restart because the battery is compleatly flat,...

If when you re charge the battery it comes back full power and starts the bike no problem then it has to be the stator circuit somewhere from stator to the battery to test this you need special meters and bucket loads of experience even mechanics usually pass electrical issues on to someone else!
sorry I would only suggest taking somewhere to diagnose this one unless you a master electrician?
One thing could be worth a shot is when a battery continually gets drained and recharged they generally end up toasted in very short time and your engine will have more cranking compression when all warmed up so will need the best battery power to re start. could be worth changing the battery and testing this theory - I would highly recommend new battery even if you get the charge issue fixed as you don't get many re charges out of them any way!

New battery. ran good for a day. next day battery dead. there is no headlight,horn,nothing!!!!. got a neww battery again and same problem workes one day next day dead. I need a salution to my problem.


Sounds like a serious drain. First, fully recharge the battery, a new one should survive. By the way, disconnect the negative terminal until you get this all resolved...

So, charged battery, fluid up. connect the battery and measure the voltage at it's terminals. Start the bike and measure voltage again. Running, at 1500 to 2400 rpm, and lights off, you need 13.8 to 14.2 volts. I bet that you may not see much of an increase.

Turn off engine, everything off, Disconnect the negative battery terminal, and put a test light in series. Does it light, if so, start probing where something is grounded. On Bikes, that is often the diodes in the charging system. That is one of the first things to disconnect and check test light at the battery... (to be clear: in series means that the test light connects to the removed negative wire, and the test light's grounding end goes to the battery. It completes the circuit.)
Keep moving and disconnecting until you have no light at the battery test light...

Another way of measurement is to remove negative battery cable and connect the leads of a voltmeter to batt terminal and negative wire.

This is the process to get what is happening. When a charging system diode fails, (diode is a one way "valve" for electricity, allowing current to move in one direction, but not the other) the power runs right to ground through a failed diode or two. They just fail eventually.

Power failure for BOSCH PSR 1440 Drill

Usually the problem is in your battery, they develop a memory, they will only charge to a certain point. This can happen when the battery is recharged when it is not completely dead.
The key is to let the battery go completely dead, before recharging. I will wait till the battery is dead, then tape the trigger down and let the drill run till it won't move any more.
Sometimes you can reverse the battery memory, by doing the above, but when the battery is that bad, you might need to start with a new battery, and make sure it is completely drained, before charging it.
Wish you the best of luck.

Dropping cylinder at 10rpm and possible generator /stater problem

It seems the charging system of your bike is not working
Recharge the battery and thn fit it in the bike and start it and check the charging rate.
Remember with lights 'on' it drains power from the battery butthe charging system of theengine takes over i.e. if its working alright, with your explanation, its for sure the charging system is not functioning.
Chekc the altenator and the rectifier.

Seems to be electrical problem

What initiated the need for jump starting? Is the alternator charging? Has the battery been checked?

To check the alternator, once the engine has been jumped and is running, remove one of the battery post connections. If the engine dies, the alternator is not charging the battery, and the symptoms you describe are the on-board computer going through low voltage spasms until sufficient electrical power to operate the engine / tranny is drained and the car dies.

If the car continues to run with no battery attached, the alternator is charging - - - and I would recommend removing the battery and having it checked and (if good) recharged to full capacity. I would also recommend having it charged even if the alternator is the problem just to delay the onset of the low voltage problems. The car should operate normally for a few miles before the battery drains too low after a full recharge, enabling you to get it to a shop for alternator service / replacement.

If you attempt replacing the alternator yourself, make sure the battery is disconnected prior to starting the job. Saves blowing up good stuff by accidental short.

Hope this helps and good luck!
