Generally speaking, when one component within the charging system goes bad (stator or regulator/rectifier), the other unit isn't far behind. It's for this reason we recommend that you replace both components within the charging system whenever there's a problem.

• 2003 Heritage Softail Stator

In your case, it's probably the stator that was bad, not the regulator/rectifier that you just replaced. The underlying reason is, when stator output begins to decline, the rectifier portion of the regulator/rectifier has to work hard to maintain proper output voltage. And, while that's exactly what it's designed to do, it can only do that for so long before it starts to fail as the rectifier circuit has been constantly taxed while you ride. So, for your bike, we recommend that you replace both, the stator and regulator/rectifier in order to be sure all is well as far as the charging system is concerned. To do that, you've already found the proper stator, just be sure to add a Drag Specialties Solid-State Voltage Regulator Of course, as I'm sure you understand, without having the bike here to examine, it's impossible to say for sure exactly what the problem happens to be. Before purchasing a bunch of parts to see what's wrong, we recommend a good check of the bike's electrical system before you get started with replacing any more parts.

To do that, if you don't have one already, have a look at the Clymer Service Manual for your bike as it'll help you nail down the problem and then go from there. There's nothing particularly difficult about changing out the Harley Davidson stator as compared to say, putting a new headlight on the bike or replacing the clutch plates.

Of course, it really depends on your mechanical aptitude and the tools that you have. Though, for most bikes, no special tools are required.

Before you start the job, however, make sure you have a Cylmer service manual on hand and study the stator replacement procedure for your bike there. The manuals come with step-by-step instructions that show you exactly how to get the job done. About the only specialty tool you'll need is a torque wrench.

5 Best Batteries for Harley Davidson Bikes Does your have a weak battery? Stop me if you know this scenario. Sometimes the engine cranks just fine, but other times you only hear an annoying ‘click, click, click’ noise when you push the starter button.

Love those days right. Of course, your first recourse is to remove the battery and charge it for a couple of hours. But if your bike suffers from intermittent starting issues (even after recharging and checking that the charging system is working just fine) then you have no choice but to buy a new battery. We get lots of from not just beginners but also experienced riders who want to do it themselves. Many riders in the scenario above want to know what is the best battery for a is, but it isn’t that simple.

The answer will depend on what type of Harley you have as well as some other factors. Regardless, there is one important thing you need to know about buying a new battery for your Harley: the CCA, or Cold Cranking Amps. Don’t worry, we’ll explain what that is below.

​Read more: What is the CCA or Cold Cranking Amps? Simply put, the CCA or cold cranking amps is the amount of power that a particular battery can produce when you start the motor.

A Harley battery with a higher CCA rating can produce and sustain more power each and every time. The bigger the motor, the higher the CCA requirement. You should consider buying a Harley battery with a higher CCA rating especially if:. ​You have an older or vintage Harley. Such as the alternator, starter, and the electrical wiring will deteriorate and age along with your bike.

This means that your vintage Harley will need a lot more power to start the motor or to turn on the headlights. Installing a battery with a higher CCA rating will make life easier for your aging bike. You installed aftermarket accessories on your ride. You may not notice it, but installing aftermarket accessories such as radios, lighting kits, winches, etc.

Will put more strain on the battery. Choosing a battery with a higher CCA rating will help your Harley cope with the increased power demands of those accessories. ​How Do They Test the Cold Cranking Amps of the Battery? In order to determine the, there are standardized tests that need to be performed by the (who knew such a body even existed). Each battery is exposed to a cold environment (hence the name ‘cold’ cranking amps), which is meant to imitate the worst case scenario when it comes to starting an engine.

About 0 degrees Fahrenheit or -18 degrees Celsius. Yeah, that’s pretty bloody cold. Measurements of the discharge load are then taken from a brand new and fully-charged battery when the motor is cranked for approximately 30 seconds. Does this test sound familiar? Yes, of course it does, it is the same thing you do if you’re based in cold climates like we are and still ride your bike when it is frigid outside (we’re gluttons for punishment). If you ever tried starting your motorcycle, car, or truck in the dead of winter, then you’ll know what this means and you feel our pain.

During the test, the battery will have to maintain a terminal voltage that is equal to or higher than 1.20 volts per cell. All of these tests will somehow give you an idea on the kind of performance that you can expect from your brand new battery, even when your Harley is exposed to chilly weather conditions. Does a Higher CCA Rating mean a Better Battery? Come to think of it, yes, especially if you live in a cold climate. But buying a new battery that has 300 CCA more than the recommended battery for your ride will not exactly help a lot. Of course, if your bike has tons of power-robbing accessories, then getting a battery with a higher CCA rating is the way to go, as long as you don’t mind the price difference between an OEM and aftermarket Harley battery. But for stock applications, there is no need to spend more dough on a bigger or heavier battery with a higher CCA rating.

However, if your Harley is heavily modified to produce more power, then you will definitely need to buy a battery with a higher CCA rating. An ordinary or OEM battery will not be able to cope with the power demands of your modified bike. It will work fine for the first couple of months, but the battery will eventually weaken or die as you ride your bike. We researched Harley appropriate batteries and narrowed it down to the five best batteries for bikes that we highly recommend. Hopefully, this will make it painless to choose the right battery for your ride.

They might be leather gloves, or cotton gloves, but most of them wear nitrile or latex gloves. That is because they are disposable and keep your hands from getting stained with dirt and oil.

They are thick enough that they won’t tear, and they will keep your hands clean from dirt, oil, and chain lube. I also like to keep a pair of these either in my motorcycle storage compartment, or in my leather jacket. Just in case I have to do some emergency maintenance on the side of the road.
