Where can i get a new alternator from?

Im assuming the alternator your replacing is on a v6 statesman.
1.disconnect battery
2.remove engine cover
3.remove drive belt
.remove 10mm bolt that holds bracket from eng to alternator
4.remove all wiring from the rear of alternator.
5.remove the 2 bolts that holds the alternator to engine.
6.wiggle alternator and it will slip out.;
7.refit new alternator in these steps but reversed.
8.once up and running again please make sure you check the system charge rate..

Could be electrical.Bikes that have generator systems need battery induced.Unlike an alternator system,like a car you can jump start and the alternator will run with good spark to fire fuel.Generator type need battery induced,so battery must have correct amperage.Can test battery with a volt or/amp test.See what you have with bike not running,then running need about 20% more volts then the 6 or 12 volt battery states (about 14 volts running on a 12 volt battery.Know your battery life span & know that a new battery that year.Plus generator must keep battery charged.I like to have a good spare and also go for a glass mat battery especially if bike is ridden season related. Good Luck!

You need to check the charging current and also the discharging of the battery in the IDLE mode.
Please check this link for some tips.

Use a multimeter to check the charging current and also discharging rate when the engine is switched off.

The alternator and accessories must be checked.

Try an auto electrician that does bikes, you can usually fit a relay/booster on starter motors to give it that initial boost, i tend to agree about your mechanics.

It wont always destroy something.
What can happen, is the pickup battery can accept a lot more amps than the bikes charge system can produce.
So when the bike starts and you give it a big rev, it will try and produce maximum current which can damage the battery or charge system regulator etc

Push\roll start can be safer, as it then only tries to charge the bike battery, which it is designed for.

Your bike will not run without a battery, Get a new battery in there, and make sure your alternator is working to keep it charged. If the alternator is bad, a new battery will only run the bike for maybe 1 hour before it dies. You might go a couple years either direction for parts to fit. Even body parts might fit. Hope this helps.

If you are buying a multitester also consider buying a small motorcycle battery charger. They make ones that have a remote charging cable that you put on the battery one time and then you have an easy way to connect the small charger up when the bike it sitting for long periods. This will keep the battery fully charged and ready to go when you are.
Some batteries are sold only partially charged and you need to bench charge them fully before running them on the bike. Depending on your bikes energy demands the battery may never fully charge up during regular use.
If you put the multitester on DC voltage check the battery to see what its resting charge state is.
If the battery is reading less than 10.6 volts its probably down too low the recharge itself using the bikes alternator. Charge it until its resting voltage is 12.0 volts. Then your bikes alternator can make enough juice at 14-15 volts to recharge the battery while its running.
Good luck and be careful.

Sounds like you are not getting a charge from the alternator. You need to check battery voltage with a meter with the engine off, key off. Then again with it running, and the voltage should increase. If not, it's not charging.

hi there . frist i check battery voltage ie fullie charged shood be a bout 12.5 to 12.75 volts this is what a bike battery shood have when fullie charged .then start the bike up and check the battery voltage agen with the head light on high beam at idel it shood be sum were around 13 to 15 volts then bring the revs up to 5000 rpm and check the voltag agen shood be above 13 volts no higher then 15 volts if this is wat you getting at the battery you need to check haw manny amps it is charging ie need a ampe meter for this it shood be putting in at least 1.5 to 2 positive amps to the battery if not the reg-rec of stator cood be faulty or a bad earth . the problem is you need the right tools for this sort of job . and alot of bike shops dont have them . try cleaning the eath temanls top and bottom check all connectors . a lot of the time it is just a bad conection

I think 13.26 is very good for a bike of it's age. Especially charging a bigger cell battery such as a car battery! I wouldn't worry to much about your charging system looks to be doing just fine. almost sounds like your bike needs to be taken out for a Relief of sitting run.
