How To Test Rectifier On Motorcycle – A regulator is a part of a charging system that converts the voltage from the alternator into a voltage that can be used to charge the battery.

Here is a picture of the Lucas alternator rotor (the magnetic bit in the center) and stator (the bit that comes out of the wire)

As the magnets in the rotor rotate, they excite coils of wire embedded in green resin in the stator.

AC is suitable for making light bulbs, but it needs to be converted to DC to charge the battery.

To give it its full name, a “full-wave bridge rectifier” uses four diodes that basically take everything below the green line and slide it above the line!

Because of the vibrations in cars and bikes, diodes in original settings tended to hum easily.

There are some newer types of tuners/regulators that cannot be easily tested because they contain microchips and specialized circuitry.

Note that some synthesizer/regulators have capacitors inside them, which will also affect your results.

If you are using a combination tuner/adjuster, please note that this test procedure only verifies that the fix pack is working properly. The regulator side is not part of these tests – you need to monitor the output of the positive and negative leads when the reg/rec is connected to a fully charged battery.

However, most tuners/tuners on the market (including Podtronics, Boyer Bransden Power Box and Tympanium) are simple and easy to test.

If you have a factory original tuner, make sure the multimeter has a fresh battery – the diode is larger than the modern equivalent.

The display reads “OL”, which means “open line”.

Once your test leads are connected, the needle will stop on the opposite side of the scale – a reading of 1.

I don’t think their explanation of the test sequence is clear. So I’ve done my best below to make it easy to understand.

You should generate a series of 8 numbers – follow the procedure below and write down the numbers so you don’t lose track.

In the following tests – tests 1, 3, 5 and 7, the green arrow indicates that you should see the reading on the multimeter.

This value will vary from location to location, but all four readings should have the same or nearly the same value.

For the rest of the tests – the STOP symbol in tests 2, 4, 6 and 8 indicates no voltage.

If you do not see the desired value in either of these tests, there is a faulty diode (diode) inside the rectifier.

Throw away the defective part instead of putting it in the workshop drawer. This will ensure that he does not get back on the bike in the future!!!

A motorcycle’s charging system is actually quite simple. Diagnosing faults is easy once you know how your motorcycle’s charging system works and what’s wrong with it.

Since breakdowns are not uncommon, knowing how to fix the charging system can mean the difference between getting 200km home or being stuck in the middle.

It also means avoiding making a stupid purchase or knocking $500 off a motorcycle’s asking price.

Well, I did. That’s why I created this website as an affiliate network. I love learning and sharing what others find useful. If you like what you read here, and you’re a section enthusiast like me, you might want to know when I write more. (Check the latest to see what you’ll see.)

How To Diagnose Motorcycle Electrical Problems

In short, there are only five main electrical components in a motorcycle’s charging system (which fail all the time).

If the motorcycle’s charging system goes wrong, one of these components has failed. The important thing is to know which one failed.

Many times, when asked about motorcycle charging systems on forums, people say “dead battery” and give an example of when they bought a dead battery from the store. I’m sure that happens, and sometimes they’re right. But don’t buy the battery unless you’re sure it’s faulty. Well, if he’s dead, we know what killed him. It’s better not to “throw the straw over the wall.” It’s a waste of money.

The main thing I’ve seen change on modern bikes is that sometimes the stator coil is not driven directly from the motor, but instead on another unit (alternator) that is driven by a belt like in a car. I recently saw this on a BMW R1200* engine, and I also wrote a guide to changing the shifter belt here.

Understanding Motorcycle Voltage Regulator Wiring

There are a number of main characteristics of a motorcycle charging system. Any of these could mean that something in the charging system is broken.

Basically, when your motorcycle won’t charge (or shuts down), it means one of the above components has failed!

Component failure in a motorcycle’s charging system can occur in a number of different ways:

Other than that, all you need are regular tools like those in your toolbox. You need to go to the battery and disconnect a few things. I’m just saying I need it

How To Test A Voltage Regulator: 12 Steps (with Pictures)

Before testing your motorcycle’s charging system, you should use the charger you purchased from Amazon or eBay. Leave overnight.

The battery must be charged before performing other tests or your results may not be meaningful.

You usually have to remove the seat to charge the battery. Sometimes you have to remove the tank – it’s not you!

Mental note: I’m very grateful to have a motorcycle (to keep me warm), but since it’s a bikini line, I have access to everything.

Once your battery is charged, you can now start testing your motorcycle’s charging system! Test the voltage with a multimeter.

Before Buying a New Battery – If your motorcycle is running fine and you suddenly need a new battery… ask yourself, “Why did my battery die?” You should ask.

If it is old, for example, the battery has never been changed, or it is more than 5 years old, then you may feel comfortable replacing the battery.

If a bad tuner/adjuster screws it up, then you’ll be wasting time and money rebuilding a new one. Test reg/rec – we’ll do it next.

Your Bike’s Charging System

Now start the motorcycle, warm it up a bit and check the battery voltage again.

Is the voltage below 12V when idle? Then something doesn’t generate enough power. You may have a short somewhere in the system that is drawing too much current, the commutator/stator circuit may be faulty, or the reg/rec may have failed completely.

Is the voltage greater than 15V at 3000 rpm? If so, then the regulator/regulator is partially fried. You can do some more testing on it (that’s a story for another day). But you can pick it up, or you can buy it by firing up a pot. At worst, you’ll need that backup (they all die eventually).

To get a deeper understanding of what part of the motorcycle charging system is not working, see if your alternator/stator coil is working.

Rectifier Or Stator Problem

Stator coil removed on old Ducati Monster 900. I really believe this is the problem before I go to this length!

You need to know if your alternator/stator coil is making enough power. You can usually tell if this is the case by checking the voltage.

A stationary coil is a coil (or series of coils) located around the rotor. The rotor is simply a magnet attached to the side of the motorcycle.

When the motorcycle engine revs – it. When it’s turned on (or when you push it to start!) – the rotating magnet spins. The magnet rotates inside the stator circuit. The changing magnetic field caused by the rotating magnet induces current in the coils. It works the opposite of an electric motor.
