What to do if you have a bad stator?

What to do if you have a bad stator?

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. Everything required can be purchased for under $50. It will work on all contact breaker point engines (old style), and some electronic controlled ignition (newer style) ones.

What does a stator on a bike do?

The stator is the set of copper coils surrounding the crankshaft. The number of coils varies from bike to bike. Mine had 2. Just a warning, if you have a lighting system, it will not work if you remove the stator. You could find a way to wire the lights up to the battery but I won’t be explaining that.

Where do you put the wire for a new stator?

The wire marked red (coming from the engine) in the diagram is going to attach directly to the contact breaker points. There should already be a wire connected to the breaker points right where we need to put the new one. You need to remove that old wire and put the wire for the new system RIGHT WHERE THE OLD ONE WAS.

How much does it cost to get a new stator?

Create a Battery-op Ignition System for Less Than $50 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.

What to do if your stator on your ATV is bad?

This is a free and easy fix so try it out if your battery is still good. Voltage regulator rectifier unit: If your voltage regulator is bad, you’ll have the same problems as if your stator is bad. This can make it difficult to determine, which is the problem. You can test this with a multimeter to see if it is working.

How can I tell if my stator needs to be replaced?

This test makes sure that the stator isn’t shorting out to the ground. Your meter should read “OL” or open line. If the multimeter is picking up a reading, it means your stator needs to be replaced. Repeat this test for each of the windings.

Can a multimeter be used to test a stator?

Some people opt to replace the stator without checking, but testing a stator is easier than replacing it as long as you have a multimeter. You can get a multimeter for $10-40 on Amazon, so you might as well just have one around for when you need it. In order to test your stator, you only need two things, neither of which is expensive.

What to do if your battery rectifier is bad?

You may need to clean the connectors. This is a free and easy fix so try it out if your battery is still good. Voltage regulator rectifier unit: If your voltage regulator is bad, you’ll have the same problems as if your stator is bad. This can make it difficult to determine, which is the problem.

How do you remove a nut from a stator?

1- To remove the nut, the flywheel must be locked in place or else it will simply turn. You can lock it in place by using a special tool. Alternatively, you can lock it this way: remove the spark plug and feed wire or rope down into the cylinder.

When do you know you need to replace a stator?

Then you know that the stator is shorted to ground and you will need to replace the stator. Then, on other stators, you can check the resistance between the wires coming out of the stator. Some of these stators will have a certain amount of resistance between the wires.

What happens if one winding of a stator fails?

Some stators will be broken down into two, three, four, or even six halves! Meaning, that one winding will produce the electricity that is used for one, two, or three different cylinders! So, if one winding will fail. The engine will lose spark on one or all of those cylinders.

What happens to the spark plug when a stator goes bad?

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.

Can a stator be removed from a Harley Davidson?

Mike demonstrates Harley Davidson stator and rotor removal so we can replace it with a 50 amp upgrade. Follow along. There are plenty of tips along the way. Did you test your system?

How do you replace a stator on a V-twin?

Unhook from voltage regulator and very carefully use some needle nose and work the plug end of wires through to the inside of engine case. Remove the four or five screws going through the stator and pull it off. Do not re use the stator screws. Even locative seems to find a way to back out. Cost about 8$ for new set.

What happens when a stator dies on an engine?

While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Symptoms are often worsened as the engine warms up. This needs to be a fairly heavy duty coil. I previously tried using two universal coils intended for small engines.

What’s the best way to replace a stator rotor?

Paint can opener tools, free from many paint stores, work great for pulling rotor. Bend about an inch of the end of each at 90° and they’ll hook right into the holes in the rotor. Good trick right there. You even get to stick your fingers through the loop ends.

How does a permanent magnet stator work in a car?

A permanent magnet stator is a stationary piece of circular metal with prongs that have lengths of copper wires wrapped around them, which are then connected into either a “wye” or “delta” pattern. The coils produce electricity as magnets on the rotor, or the flywheel, move around the stator.

What do I need to replace my stator on my Harley?

First thing you need is the “thick Harley Manual” for your model year bike (not the skinny one that comes with the bike when you buy it)…if you don’t have one already, I highly suggest buying one from your local dealership. It will take you thru it step by step with pictures of everything that your wanting to do.

How does a field excited stator work on a bike?

The stator produces alternating current (AC) that flows into your machine’s rectifier to be converted to direct current (DC) and then power the DC loads on your bike. Field excited stators are similar to permanent magnetic systems, except they operate with an electromagnet instead of permanent magnets.

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.

Why is the regulator on my Harley stator not working?

The regulator protects the battery voltage and when the battery voltage climbs too high it shuts off current to ground and bleeds it off as heat. That is what the heat fins on the regulator box are for, to dissipate the heat. If the regulator did not monitor the voltage to your battery it would destroy it.

How do you test the ground of a stator?

Ground Test. Set your multimeter to Ohms. Put the negative lead on the engine’s ground and the positive lead on each wires of the stator’s connector one by one. You shouldn’t get a reading at all. If you get a reading, even very small, on any wire, the stator is defective and must be changed.

How does the stator work on an engine?

The stator is made up of windings that produce alternating current electricity. As the magnets on the flywheel spin around the windings when the engine is running. This AC electricity is used by the engine to run all of the ignition components of the engine.

How can I tell if my stator connector is defective?

Ohms Test. You will need a multimeter set to Ohms for this test. Test every lead of the stator’s connector and note the readings. The reading of each combination should be the same (test leads 1-2, 2-3, and 3-1). If they are different, your stator is defective.

How do you install a stator on a Harley Davidson?

Reinstall the derby cover and loosely screw the Derby cover bolts into place. Tighten the bolts to 6 foot-pounds, alternating between bolts in a crisscross pattern. Reinstall the front and passenger foot rests or floor boards, as well as the side stand.

How is a stator attached to an engine?

First the easy: attaching the negative (black) wire going to the engine. This wire can be attached to any conductive part of the engine assembly. On cars and motorcycles the metal parts of the engine are in electrical contact with each other, which causes them to make up one large electric terminal.

How does a stator work on an ATV?

Think of it like your car’s alternator. Stators can look quite different depending on the brand of ATV and model, but in general, they consist of an iron core, wire coils, and a cable that allows the stator to be connected to the voltage regulator.
