Dies after two hours driving

My bike is only running 12 volts at the battery terminals at 2000 rpm. It dies after about two hours of driving on a full charge and I need to know where to look and what to check to get the battery charging again while it's running

May be the rectifier or voltage regulater, use test meter to see what voltage is at the regulater

  • xsrider Jun 16, 2011

    From your description the bike is obviously not charging. Take a look at the rotor and or rotor brushes. The rotor's resistance across the brushes should be around 5 ohms.

    Remove one wire measure the resistance. If less than 4.25 rotors is bad. If greater than 6 ohms the brushes are not conducting, possibly seized in the holder.


    Here is a link to a CD presentation that teaches you all about your 650's electrical system and step by step how to test the charging system. Well worth the investment.

It could be you have a fault in the Diode pack in the alternator you need to get this checked at an alternator repair center.

Starting problem
Did you charge the new battery before fitting, this is most important.
Is the battery a top up/ gel or MF type. Top up and MF need acid to work, was battery filled with acid? If you do get the bike running check the charging rate of the alternator by connecting a multi meter to the battery terminals. A 12 volt battery should show 12.5 to 13.2 volts off the bike and around 14 volts on the bike with the engine running at 5 K revs. (half throttle).

More likely to be your ignition coils. They heat up and expand this can cause an open circuit which will close up again when it has cooled down. Although, a bad charging system may cause this problem. Check the battery voltage with engine switched off ( approx 12 volts) and with the engine running (approx 14 volts) If you are getting 14 volts then your battery is dead, if you aren't, then your charging system has a fault.

My Whizzer motor bike will fire, but wont turn over and start
If you battery had a standard reading of 11.5 volts that drops down to .5 volts when you put load on the battery, your battery has gone bad. A healthy battery will give you a static reading of around 12.6 volts, and that will drop to about 12 volts when you're starting the bike. Conversely, when the bike is running, you should see 13.5-14.5 volts across the battery terminals. That shows that the alternator is charging and that the battery is good.

I have a vehicle with a battery going south. I have a static voltage of 12.16 volts, and I only get about 13.2 volts across the terminal when the car is running and the alternator is charging the battery. Soon, it will be time to change out the battery.

Hope this helps!

I have a 2001 flhtcui what are the ac reading coming from stator at 2.5k rpm 3k rpm and 3600 rpm. At 2000 rpm I get about 12 volts dash guage reading but at 3000 I get 13.5 to 14 at lower rpm 2000 or so I...
The AC output of the stator should be 32-40 volts at 2000 RPM (16-20 per 1000 RPM). With the battery fully charged, your regulator should supply between 13.5 and 15.0 DC volts to the battery. This should be the reading you get on your voltmeter. It will vary depending on what lights and other equipment you have turned on. Sounds like everything is working fine to me. The gauge is reading the DC voltage at the battery while the engine is running. At 2000 RPM, 12 volts is a little low but, considering the accuracy of the gauge, as long as it doesn't fall below 12 volts, it's about right. You don't ride for extended periods at engine RPMs that low. Then at 3000 RPM, 14 volts is about right. If your bike never ran anymore than 12 volts, your battery would slowly go down. If it goes any higher than 15.0 volts, it will boil the battery. Usually, about 14.3 or so with no load on the system is about right.

Good Luck

Put a charger on the battery for two or three hours. Now start the bike up and use a voltmeter to measure the voltage across the two battery terminals while the engine is running around 2000 rpm. The meter should read around 14 volts. If not, the charging system needs to be checked. If the charging system is working properly then yes, something is draining the battery. You will need to check all the wiring and switches to locate the source.

I have a 2006 gsxr 600 if i jump start it , it will start but when i disconnect the cables it turn off
Sounds like either the battery is dead, or one of the connections to it is corroded. Remove the battery from the bike, check the water levels (replace low water with distilled water, not tap water), place it on a low-current charger for at least 12 hours. Clean and check the wiring and terminals that connect to the battery. If the battery is any good, it should now start the bike and keep it running. With the engine running, read the battery voltage with a DC voltmeter--it should read at least 13.5 volts. If it only reads 12.6 volts or less, then the bike charging system requires service. Hope this helps!

Yamaha dt 175, voltage question. When idling, my DT measures 7 volts across the battery terminals. When revved it jumps up to over 13 volts. This is a six volt bike. I know the battery is completely shot....
You need new regulator and new battery.The battery works as a filter as well.If it is in bad condition it does not filter anything and in high rpm the current is very high.
