Dead or weak battery?
A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
Bad alternator- not charging battery enough to keep vehicle running check with a volt meter A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
Check to see if the alternator is working Connect a voltmeter to battery: Without engine running reading should be about 12.8 With engine running reading should be 13.8-14.2 If not bad alternator
Perhaps the alternator is not charging the battery adequately check with a voltmeter A fully charged battery should read around 12.8 (without engine running) With engine running reading should be 13.8-14.2
check the battery with voltmeter without the engine running then check with it running if voltage is higher it is working
Check alternator output with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running Should read approx. 13.8-14.2 with engine running
Yes you can but not with the engine running. If you do this the alternator will kick in and transfer more amps than your bike can handle. Jump start it from a cold battery without the engine running and you'll be A OK!
Check alternator with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running With engine running reading should be approx. 13.8 - 14.2 volts
Perhaps alternator is not charging battery sufficiently, test with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running With engine running reading should be approx. 13.8-14.2volts
Age of battery Battery will not hold a charge (check with a volt meter) A fully charged battery should read approx. 12.8 volts (without engine running) If charging system is working properly reading should increase to approx. 13.8-14.2 with engine running. If voltage does not increase with engine running could be a problem with charging system of battery is defective and will not take or hold a charge
A fully charged car battery will read 12.6 volts, 75% charge will read 12.4 volts, 50% charge will read 12.2 volts, and a 25% charged battery will read 12.0 volts with the engine not running. With the engine running it will read 13.5 to 15.5 volts.
If you leave the Ingition Switch on without the engine running. The battery will go dead. Then you will have to get a boost or charge the battery to get the engine started.
