What causes motorcycle stator failure?

The two most common causes of Stator failures in our design will be through not changing the oil+filter and coolant at the correct service points. Old oil slowly becomes acidic and abrasive and also causing the engine to rum warmer than needed this causing premature engine component wear.

What can cause a motorcycle 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.

What can cause a stator to fail?

When a stator fails, it is largely due to the degradation or aging of its insulation through external occurrences and materials being introduced into its system.

What are the symptoms of a bad stator on a motorcycle?

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.

Can a stator be repaired?

In many cases a new stator is the safest, most cost-effective solution for an electrical system breakdown. Because repairing stators can be an intricate and detail-intensive process, replacing failed stators with an entirely new part can be a much easier route, depending on the specific motorcycle.

Can a bad stator drain a battery?

When a stator has gone bad, that means the motorcycle is running off of battery power alone which will quickly drain it. … Batteries aren’t able to store AC current so the regulator/rectifier converts power into a type of current the battery can store.

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.

What are the signs of a bad rectifier?

Key Signs to Look For

First, the diode can burnout and cause the battery to drain. 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.

Will a motorcycle run 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.

Can you ride a bike with a bad stator?

If the stator is bad, the bike won’t run at all. The stator generates energy for spark. Assuming the air cleaner is clean and other general maintenance has been performed, if the bike won’t kick start but runs as you state, the problem is probably either the spark plug and/or fuel delivery.

Will a Harley start 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.

How much does a stator cost?

The Stator is priced at $3,995, though you’ll only need to put down $250 to reserve your own Stator. Just try not to think about how that same $250 deposit could buy you an entire Amazon electric scooter.

What tests can be performed on a stator?

These additional tests include voltage withstand testing, insulation resistance, polarization index and dc winding resistance measurements, as well as inter turn fault detection. They assess not only the insulation integrity, but also help to identify connection problems and weak points in the stator winding.
