To determine if the issue lies with the voltage regulator or the stator, first check the voltage output from the stator using a multimeter. If the stator is producing the correct AC voltage but the battery isn't charging, the voltage regulator may be faulty. Conversely, if the stator is not generating the required voltage, it is likely the stator that is bad. Additionally, visual inspection for signs of damage or overheating can provide clues about which component may be failing.

What causes a new battery on a 2002 Ultra Classic to die?
The voltage regulator is bad or the Stator. Check to make sure you do not have something pulling power when the key is off.. Check the voltage should be 12.5 to 14.0, if it is lower then 12.5 with the engine running at idle. Check the stator for ground if the stator is grounding out bad Stator. If not, bad voltage regulator
What is a motorcycle voltage regulator?
A voltage regulator converts a/c volatge from the stator to dc voltage and regulates it down to under 15 volts. When they go bad they can over charge and take out a battery as well as not charge at all.
How do you know if a regulator is bad on a 1989 harley Davidson?
Check your stator first. That is the two wires coming out of the front of the case on the left side. With the bike running it should read about 18VAC. The two wires go directly to your regulator. Check the output of the regulator. You can do this at the battery. A charged battery should read between 12-13VDC (bike not running). Start the bike. Check for DC voltage at the battery again. It should read 14-14.5VDC. If you are only getting battery voltage with the bike running (1500-2000RPM) and the stator (rotating assembly) is putting out 18VAC +or- 1VAC your regulator is bad.
How do you know if a stator is bad on a 1989 harley Davidson?
Unplug your voltage regulator at the front of the crankcase on the primary side. Use a multimeter set to "AC", by inserting the probes into the two holes and rev your bike to about 2500rpm or so. You should get about a 40-60 volt reading. You should also check for a ground, by doing a continuity test, or use the OHM setting on your multimeter to make sure the stator is not grounding out. If everything is good there, and your not charging up, your regulator is bad.
Why would the battery in a 2004 Harley Davidson Heritage Softail not stay charged?
Many reasons are possible. Bad battery or discharging due to a short in the wiring or bad voltage regulator or stator is bad. Just too name the most common.
How will you know if you have a bad voltage regulator in your car?
You will need to go to a repair shop and have them test the charging system.
Why do you keep blowing your headlights and taillights everytime you ride your snowmobile?

What would be causing your battery to drain on your 2000 Harley Davidson FLHT?
Might be a defective voltage regulator (not opening circuit on shut-down) Or a bad stator. (if the battery doesn't charge at all.) Or an electrical short.
Where is the voltage regulator on a 1991 Toyota Corolla?
how will I know my Voltage regulator is bad. I have replaced the starter and had the battery and alternator checked they are good. My car will start when it is colder outside but as the day gets hotter it will not start.. Can you help
What would cause all running lights to flicker burn bright then go out--with the battery becomming literally smoking hot?
You have burnt out your voltage regulator. I would put money on your stator being bad now too.
Why is the voltage regulator overcharging the battery in a 1990 Ford econoline?
A bad voltage regulator can cause an overcharging condition. Check the wires going to the regulator for corrosion and make sure the regulator has a good ground.
How do you know if the voltage regulator is bad on a 2007 Dodge Durango?
To determine if the voltage regulator on a 2007 Dodge Durango is bad, check for inconsistent voltage readings using a multimeter. If the voltage fluctuates significantly or is consistently below 13.5 volts while the engine is running, the regulator may be faulty. Additionally, look for symptoms like dimming lights, electrical issues, or a warning light on the dashboard, which can also indicate a problem with the voltage regulator. If these signs are present, further testing or replacement may be necessary.
