Isn't starting. battery isn't getting a charge. bike starts once the battery is charged

you need 12.6 to turn on the regulator to allow it to charge at 14.25..and than should read 13.75 on shut down..till the battery cools back to 12.6....no 12.6 no charge...new battery needed

Sounds like a charging problem. Charge the battery, then start the bike. Run the rpm's up to 2000 while checking voltage at the battery with a volt meter (dc volts). Voltage should be 13.8-14.2dc volts. If you don't get close to these readings, the charging system isn't working properly.

your charging system isn't working, if you replaced the battery and it worked for a few days, then its not being re charged after starting, I'm assuming you cleaned and tightened all the battery post connections when you installed the new battery , if not do so ,, charge the battery from an outside source, once you know its fully charged,, use a meter, and start the car ,, check the voltages at the battery posts,, you should be getting a reading of 13.5-14.5 volts, if not your alternator isn't charging the battery

Bike batteries need full charge to start a bike, if there is less than full charge you can't even push start them. No click generally means no charge, the clicking sound is the solenoid working.
When you just start the bike and run it at idle, even fast idle. The battery does not get sufficient charge. What you take out of it to start it, is more than what you put back in it when you run it at idle. Bikes need to be at road speed to charge efficiently.
Also just sitting around they discharge, you may have an earth leak also. That causes your battery to discharge at a more accelorated rate than normal. If it has a clock in it, this bleeds off a small amount of power but still enough if it isn't being correctly charged.

It's the alternator...it is not keeping your battery charged. You can remove it and take it to a local parts store and they will test it for free.

One explanation for this would be that your charging system is faulty. It is possible that the OLD battery was ok, but was not getting charged by the faulty charge system. You put in a new battery, that is part charged before sale and ran the battery flat because it wasn't charging. If you leave a discharged lead acid bettery for 20 minutes or so, it will pick up a little again and possibly let the bike start and run, but by the time you got home you had killed the battery completely.

All the facts fit, though I'm not promising that it is the problem.

Take the battery off and charge it with a charger. Now, put it back on the bike and run the bike (It should start) While the battery is on the bike, get a volt meter on it. It should read slightly over voltage (doesn't matter if its a 12 or 6 volt system, it will read a little over when the bike is running) when you turn the engine off, you should see the volt meter drop down to the stated battery voltage. If you get no hike with the engine running and drop as you power off, its a good sign the charging system is faulty. A similar test, start the bike, meter the battery and turn on the indicators, stop light and head light to pull as much power as you can, the battery voltage shouldn't dip, because the charge system should compensate. If it does dip, consider this a confirmation that the charging system is faulty.

Sounds like you battery isn't holding charge overnight. If it was the alternator, it wouldn't start during the day so the alternator sounds fine.

Make sure the battery that is on it is the right one for the bike.

Try taking the battery off the bike and using a battery charger to charge it overnight. If that doesn't work, I'm afraid it's going to need a new battery.

Good Luck

New battery first then look in to a coil and or magnito what ever it has for its charging system its not charging so ask a mechanic what you have then fina new one possible magnito??

Sounds like your battery has become disconnected or is damaged (dead) or isn't charging from the bike.
Try putting a charger on the battery overnight and see if you have lights in the morning.
If you do, then measure the voltage at the battery before and after starting the bike.
If the voltage is the same or less after starting, then there's something wrong in the charging circuit.
This could be a regulator, or rectifier etc.
If the voltage DID go up after starting, then it may be time to replace the battery.

sounds like your charging system went out, this isn't a new problem to bikes and alot of older bike have this issue. First was your car running when you jump started your bike?? If so this can cause damage to the charging system. if your not sure how to replace the stator and reg/rec i will happey to help you get it done. please understand that this does take some thinking and removing the tail, left hand body parts and the lh side cover of the motor. If your will to take it on let me know. If not your local bike shop can fix your bike in about a week if they have to order parts. the stator on your bike isn't the cheapest and reg/rec isn;t that bad as far as price goes. you'll need oil a filter and a new gasket for the motor cover and the charging system parts.
let me know what you would like to do.
