Without a stator, your motorcycle will not get any spark at all as your battery is not capable of supplying the appropriate power levels to generate a spark. As a result, if your stator is going bad your motorcycle will run very poorly. Eventually, your stator can prevent your motorcycle from starting at all.

Will a Harley run with a bad stator?

All the current required to run your motorcycle comes from your battery. The stator system charges your battery and replenishes it. You could actually run your motorcycle just fine for some time without a working stator as the battery has reserve current. Of course, the battery would eventually die.

What are the symptoms of a bad stator on a Harley Davidson?

The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.

How do I know if my stator is bad?

Insert each probe into a stator socket. You should read around 0.2 to 0.5 ohms. If you show an open circuit with the “Open” or infinity reading or have higher resistance, then the stator is bad and you must replace it. If these tests all produce positive results, then the stator itself is good.

How do I know if my stator or rectifier is bad?

Key Signs to Look For

You won't have any trouble diagnosing the faulty regulator rectifier if the battery is the cause. You'll note signs right away like poor starts, fluctuating meter readings, and dimmed headlights. around 13 volts, the bike will start to drain the battery.

How to check and replace your HARLEY DAVIDSON stator (Charging system issues)

Will a motorcycle start with a bad stator?

Without a stator, your motorcycle will not get any spark at all as your battery is not capable of supplying the appropriate power levels to generate a spark. As a result, if your stator is going bad your motorcycle will run very poorly. Eventually, your stator can prevent your motorcycle from starting at all.

Will a bad stator drain a battery?

Will a bad stator drain a battery? As far as the battery, yes a bad stator/regulator can destroy a new battery. If it's run at a very low voltage without being recharged then it can be destroyed. ... In most cases if we replace a stator or regulator the battery has to be changed as well as it won't hold a charge.

Does a stator charge the battery?

In simple terms, the battery provides this power. The battery would quickly be depleted, though, if not for the star of the charging system show, the stator. Think of your stator as the piece that makes electricity to keep your battery charged up to make all that electrical stuff on your bike work.

Will a bad rectifier damage a stator?

If the rectifier/regulator failure results in too low resistance the stator probably will burn (too much current). If I disconnect the rectifier/regulator the voltage will go up, but how high? Is it possible that the voltage will go high enough to destroy the isolation?

What causes a stator to go bad?

To answer why stators fail, it is because the coating on the windings breaks down, usually because of heat, causing a short which can also burn the fine wire of the winding in two at the short causing an open circuit. The way to prevent failures is to prevent the heat.

How much does it cost to change a stator?

Stator & Rotor

A new stator and rotor set typically costs between $250 and $1,500.

What happens when a stator fails?

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.

What are the symptoms of a bad CDI box?

Symptoms could include misfiring, dead cylinders, backfiring, bizarre tach behavior, and countless other things related to how your engine's running. The problem may get worse as the bike warms up. It might not even hold low revs at all.

How many volts should a Harley stator put out?

The object of this test is to see if the stator can produce proper AC voltage per 1000 RPM. For example a 32-amp stator should put out 18 volts AC (VAC) per each 1000-RPM. At 2000 it should be 36 VAC (18x2). At 3000 RPM it should be 54 VAC (18 X 3).

Can a motorcycle run without a battery?

In modern motorcycles, battery is an integral part required to start the engine. ... So, can your motorcycle run without a battery? Most modern motorcycles cannot run without a battery. If the battery is at marginal health and some life is still left in it, motorcycle can be started with a push/bump start.

What are the symptoms of a bad voltage regulator on a motorcycle?

• Motorcycle won't start. This one's the big, obvious one. ...
• Spluttering as you drive. When voltage is low, it's hard to keep the motorcycle running.
• Lights light up and dim as you rev. ...
• Battery warning light comes on.

Can you bypass a stator?

The cost of a new stator can be hundreds of dollars. 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. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly.

Will a bad battery make a motorcycle run bad?

So, does the battery affect motorcycle performance? A motorcycle battery will not directly affect the performance of your motorcycle. It can, however, cause other components and systems to operate inefficiently which ultimately can reduce the performance of a motorcycle.

Is a stator the same as an alternator?

Stators are inside the engine case. An automotive style alternator is a fully self-contained, externally mounted unit that creates DC current. Another difference between stators and automotive style alternators is the type of magnet uses. Stators use a permanent magnet, and automotive alternators use an electro-magnet.

How many volts should a stator put out?

For each 1000-rpm, a 32-amp stator should have 18 volts AC (VAC) per it. It should be 36 VAC by 2000. 54 VAC is what it should be at 3000 RPM. Each system should produce a certain amount of electricity.

What is a stator on a Harley Davidson?

The stator is an integral part of your Harley-Davidson Softail motorcycle's charging system, generating an electrical field that is manipulated by a rotating magnetic flywheel to generate an alternating electrical current.

How many volts should a Harley battery have?

The majority of Harley's build in the last 50+ years are predominantly using 12-volt batteries. However, older Harleys do use 6-volt batteries.
