Question about 2001 Yamaha V Star 1100 Classic

1 Answer

Charging problem Ok, this one is gonna be a shot in the dark. My vstar 1100 is having a charging problem. At first, I just thought that it was the battery, so I changed it out. So, after another long ride my bike went dead again and had to push start it. When I got it home and charged the battery I then checked to see that it was holding a charge, and it does at about 12.9. When the bike is started and after it is warmed up, voltage drops to about 12.7v. I was under the impression that at idle it should be between 14-14.9v at idol. I double checked all of my ground points, cleaning each and checked all ground wires for any damage. Looked normal. So I checked the stator at this point and at the OEM plug at the back of the stator, I was getting 39v AC. When the bike was stopped I was getting about 1ohm resistance. A guy at the dealership told me it was a bad stator, so I ordered a new one and installed it. I am still getting the same readings as before. The only other thing I can think of is the rectifier being bad, but I thought when they went bad they put out too much voltage not too little. Any way to test it?? Well, thats it. Hope that someone out there is able to help me. Thanks for reading this.

More than likely it is the regulator rectifer yes the some times charge to high but not always that is the best bet the origanal stator sounded like it was fine the regulatetors are trickey to test because there are so many power sources on your bike lights,display sensors so on the regulator will more than likley fix your problem

I just replaced stater and rectifier on 1100 vstar bike won't start not getting fire why isn't it

Did you check your battery? A good battery should read a minimum 12.6V at rest. Anything lower is no good.

The fact that you said you had to replace the stator and rectifier tells me you were having charging problems which also means your battery is probably shot.

My wifes vstar wont start put new battery in and starting sisinoid,still just buzzes unlett i boost it

check your charging system components from the grounds, diodes, to the stator/generator and fuses. first check the battery with a volt meter to see if it reads any voltage going back into the battery. that will tell you it is not charging. also if you want a less reliable test, try disconnecting the ground of the battery while it is running. if it stops the system is not charging.

If you need further help, reach me via phone at

My 1100 mobile phone showa not charging

There are several reasons, like bad battery, bad charging connector, bad charger, charging pin problem, charging ic, etc..
You need to try with another charger and with another battery. If changing the charger and battery don't help, follow the instructions below;
First, remove the battery, clean the contact points on the battery and also clean the battery interfaces on the mobile. You also need to check the charging connector and clean whatever is possible. Use soft brush or cotton with Ipa solution or alcohol/spirit/acetone to clean all the metal contacts. Try charging again.

If the above method don't help, you need to change the charging pin;

Still the problem persists, then check the charging ic. Perhaps jumpering will be necessary.
If you are not sure what you gonna do with ic, I don't recommend to play around with it, rather take it to a mobile repairing shop or nokia service center and get it fixed. You may damage another components.

I wish you good luck.

Thanks for using FixYa.

Battery keeps going dead

Hi and welcome to FixYa,

To your query, there are 2 major components of the charging system:
  • stator - left side of the engine itself;
  • regulator - right side, below the seat; would be behind the chrome cover below the battery.

A common problem with a VStar is burned, pitted or corroded terminal pins/connectors from the stator to the regulator.

Good luck and thank you for asking FixYa.

SB600 Works Erratically...

If red light on flash is blinking, flash is charging. In shooting rapidly, sometimes flash will go off even though it isnt fully charged. This can give dark shots. Flash eats batteries like crazy, best to always use fresh batteries for each shoot.
