I changed the regulator/rectifier, the stator, and battery but my 2002 Vstar 1100 is still not holding a charge. What to check now?

You need to check if there any bad grounds,
if you have any aftermarket lightining those may couse killing the battery. or have your battery checked or tested.

SOURCE: 2001 yamaha r6 keeps going dead! Stator,regulator or something?

you need to check for a short if its not that then it could be your altinator or a regulator box

SOURCE: Charging problem

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

SOURCE: wire connector between stator & voltage reg/rectifier burnt

your voltage/reg. can be tested in a couple different ways check ground res. check res. then revs. bias on diodes you have ac in dc out it sounds like you may have a diode gone bad allowing ac curent to flow causing the wires to get hot

SOURCE: have a 2002 vstar 1100 custom. where is stator

Just remove the left cover. The stator is bolted to the cover on the inside. Could you take a moment and rate my answer? Thanks!

SOURCE: where is the battery location for my 2007 vstar

Battery is under the seat. Buy a battery tender and keep it hooked up when not riding in the winter. If you are in an area of the country where you can ride year round then a battery tender is not necessary. Battery will probably last 3+ years if properly maintained. I owned a 2000 V-Star 1100 Classic and it was a fine bike.

Hi I have a aprilla sport city 125 the problem is that while the Bick is running the battery does not charge

Its better u take it to a motorcycle service, they can check the voltage that the scooter produces to charge the battery, maybe its the regulator or the magnetic field.

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.

How to test rectifier.

there are several ways to test a rectifer the quckest way to check if it is working properly is with a voltmeter first check ground resistance one lead to good known ground (battery neg.) the other to rectifer should be 1 ohm or less.Then hook meter to battery and start the bike and check and watch battery voltage should start to increase after a minute or so check at 2000 rpm again increase if it does not check stator if stator passes replace rectifier

My battery wont charge and I just bought it

Hi and welcome to FixYA,

Two possibilities:
  • rectifier / regulator combo (most likely);
  • corroded, burned, loose connection from the stator to the regulator (likely);
  • faulty stator (least likely).
The stator would be producing relatively high AC voltage while revving the bike. The stator output AC voltage are fed to the rectifier / regulator through 3 white wires. Check calls for testiing for the presence of the AC voltage on any pairing of the white wires before and after the connector before the voltage regulator. Check on the regulator calls for checking the battery voltage when revving the bike (14.5 VDC).

Good luck and thank you for asking 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.

2002 suzuki intruder vl1500 not charging battery

Check the voltage across the battery with the engine running - it should be greater than 13.5V. 
If less, then you have a failure in your charging system, either the stator and/or the Rectifier/Regulator. 
See this personally authored diagnostic guide on how to determine which part is defective. Also has a recommendation for excellent replacement as opposed to std OEM.

Bike not charging

Sounds like regulator/rectifier, stator, or charging rotor.
