Why is the regulator on my Harley stator not working?
The regulator protects the battery voltage and when the battery voltage climbs too high it shuts off current to ground and bleeds it off as heat. That is what the heat fins on the regulator box are for, to dissipate the heat. If the regulator did not monitor the voltage to your battery it would destroy it.
When to buy a new stator for your engine?
I devised this system when the stator on my Honda XR-100 got so weak that it couldn’t power the spark plug, preventing the engine from running. The stator on my model happened to be discontinued, and I didn’t want to buy a used one for over $100 when this particular stator is known for being weak and prone to failure.
What happens if you don’t have a stator coil?
The stator coil generates the power for the spark plug and other accessories on small engines Without a stator there would be no spark at all, meaning the engine won’t run. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Symptoms are often worsened as the engine warms up.
Where are the stator wires on a Harley Davidson?
If you have a short to ground then you have no output from the stator. Find where your 3 stator wires are. On a Harley, this is up front near where the inner primary connects to the motor case. Right by the seam. The three wires will track straight from there to your regulator/rectifier.
What should the voltage be for a stator Charger?
A good rule of thumb is you can convert to power by multiplying the stator amps ( current) x the battery ( voltage ). You can use 13 as a good all around battery voltage. That is a good healthy battery staying charged just above 12 volts. Example only: Let’s say the stator is rated for 10 amps x 13-volt battery: 10 x 13=130 watt charging system.
What kind of regulator does a Harley Davidson use?
The standard Harley regulator uses an electrical component in it called an SCR, silicon controlled rectifier, which is a little electrical switch. When the regulator sees your voltage climbing to high to the battery it shorts the stator wires to ground, which kills all the output from that leg of the stator.
What should I do if my Charger regulator is not working?
Assuming your rectifier part of the unit is still working, you’ll see current flowing to your battery. You will see your battery voltage increasing because it has current flowing into it. If you suspect the regulator part of the unit is not working, you can set your multi-meter to the “DC Volts” setting, generally a 20-volt setting.
What should the charging voltage be on a Harley stator?
You can use 13 as a good all around battery voltage. That is a good healthy battery staying charged just above 12 volts. Example only: Let’s say the stator is rated for 10 amps x 13-volt battery: 10 x 13=130 watt charging system. So you have a 130-watt charging system in this example.
What to do if you have a bad stator?
Without a good stator, your engine will run poorly or not at all. This solution completely bypasses the stator by using a 12 volt battery to power the ignition system. Everything required can be purchased for under $50. It will work on all contact breaker point engines (old style), and some electronic controlled ignition (newer style) ones.

How to test the rotor on a Harley Davidson?
Each of the following tests isolate the stator and rotor. If the AC Output test fails and Resistance Check and Stator IB Test pass, then the rotor is at fault (Pull primary covers and inspect rotor for damage). Unplug the regulator plug from the stator. Start motorcycle and change Voltmeter to AC volts.

When the regulator sees your voltage climbing to high to the battery it shorts the stator wires to ground, which kills all the output from that leg of the stator.
Is there an aftermarket regulator rectifier for Harley Davidson?
Introducing the Rick’s Motorsport Electrics regulator rectifier for Harley Davidson® motorcycles. This aftermarket Harley Davidson® Regulator Rectifier has been built with ceramic hybrid technology. It’s a perfect solution for replacing your bike’s OEM regulator rectifier.
What is the voltage regulator on a Harley Davidson?
The Harley-Davidson voltage regulator is an electrical component that controls the amount of voltage going into the instrument gauges, speedometer, and gauge cluster. It’s required by the motorcycle electronic system to display the engine speed and other important vitals.
What to do when replacing a Harley Davidson regulator?
When replacing your Harley Davidson ® Regulator Rectifier always check the connectors and wires for damage/corrosion from overheating issues. Any products with the trademark, name, word, or OEM part number used on this website by Rick’s Motorsport Electrics, Inc. is intended to be as a reference only to the usage of that particular product.
