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.
Can you start 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.
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.
Can an engine run with a bad stator?
Yes, certain outboards will run with a bad stator, but not very well. No, other smaller outboards will not run with a bad stator. The stator produces the electricity that the engine uses to operate the ignition system to run the engine.
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 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.
What happens when rectifier goes bad?
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. … If the regulator rectifier can’t moderate the voltage levels, the battery will overcharge. You can also use a voltmeter to diagnose overcharge.
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.
Will a bad rectifier damage a stator?
Bad rectifier mostly caused by toasted diodes, This made no current output, only voltage at output or input of rectifier. That means open circuit, no effect to stator winding.
Will a motorcycle run with a bad Rectifier?
A rectifier converts alternating current (AC) to direct current (DC) to charge the battery. … Since motorcycles require battery power to start them up, a bad rectifier will eventually result in the motorcycle not able to start.
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 symptoms of a bad voltage regulator on a motorcycle?
Symptoms of a bad motorcycle charging system
- 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.
What are the symptoms of a voltage regulator going bad?
Bad Voltage Regulator Symptoms
- Too High Voltage in the Battery. There are two ways a voltage regulator can fail. …
- Dead Battery. …
- Battery Light or Check Engine Light. …
- Inconsistent Operation of Electrical Components. …
- Vehicle Dies While Running. …
- Dimming/Pulsing Lights.
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.
