I was told that you have to charge the battery in ktms. That they don't charge themselves while the motor is running like a car. This is coming from a guy who has a 400sx and put the starter on it. He has to trickle charge the battery before every ride (or after I guess) Tell me this isn't true!I have an '03 525 EXC and my battery died after a day of riding and using the happy button. I could still kick the bike over which makes me think that the battery isn't required for the normal operation of the bike. Anyway when I got home I pulled the seat/covers/tank off and checked the votage accross the battery. It was around 11.4V. I started the bike and measured again. Still 11.4V !!! I finally decided to check the voltage regulator and BINGO a wire had not been correctly inserted into the plug from the factory !! I reconnected it, kicked her over and now the voltage accross the battery measures 12.2V !! So, the answer to your question is that the battery is constantly charged when the bike is running, and there should be no need to charge it unless it has run down by overuse of the starter or some phantom power sapper,,,

Got a db50qt-16 directbikes it wont start off the electric start !


Hi, I would start by checking there is a click when the button is pressed, if that is ok then that means the starter relay is ok, then I would put some jump leads and use another battery, just to make shore your battery is discharging enough power, if it still doesn't work take out the starter motor and connect it to the battery just to see if it is ok

400 burgman wont start


Are you sure battery is ok, try connecting the battery to a car battery (still in car) and start it again. This happens when battery has charge but is too weak to deliver lots of power to starter motor.

I have no power charged battery was ok before now no power check the fuses there ok can you tell me why i have no power please


it seems that the battery is not charged or not connected. When you open any door the light inside must turn on. When not, the battery is not charged. Charge the battery and try again.
When the battery goes again out of the power, it indicate that the charging system or alternator are not working properly.
Start your vehicle turn the headlamps on and check the voltage on battery. It must be higher than the voltage when engine is off.
If the voltage with engine on is about 14,5 V charging and alternator are ok. Maybe the battery is dead.
When the voltage with engine on is higher than with engine off but not 14,5 V, there is problem with charging system. When the volage is the same, it can be alternator or charging system.

No power from the battery


definatly check all the fuses. If they are ok check all the connestion blocks between the battery and the ignititio. If that dosent work check you have a solid connection for th negative. If all them are ok then it can only be the ignitition system or the battery

Battery light won't go out. volts after charge is 11.9. ?????


Sounds like you need a new battery . It is not 12 volts . Try hooking your bike up to another 12 volt battery( you can use jumper cables) Warning: It is OK to jump a motorcycle from a car battery even if the battery is still in the car. DO NOT HAVE THE CAR RUNNING. OK TO JUMP, IF THE CAR IS TURNED OFF!!! Do not crank your bike too long , you could over heat the starter. Anyway hook up your motorcycle to a good battery and start your motorcycle to see if the battery light goes out.

Fail to start


I think I would change the petrol in the tank as it may have become a bit stale. Also I would replace the battery.Make certain the replacement battery in fully charged before you try again.
