Your question: Will a snowmobile run without a stator?

Registered. As I understand it, the short answer is no. Your problem would be the lighting coil. If the stator is bad you’re not going to run or have lights or anything though these symptoms my be intermittent or progressively get worse.

Will an engine run with a bad stator?

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.

How does a stator go bad snowmobile?

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 are the symptoms of a bad stator on a snowmobile?

Runs good at lower rpms but runs bad at higher rpms (High speed coil is going bad) Backfiring and just won’t run good. Sled slowly loses power during the course of the day. Spark plugs keep getting richer/darker as the day goes on indicating weakening spark.

Do snowmobiles have stators?

A snowmobile stator is an electrical component inside the engine that is responsible for generating electrical current for everything on your sled, from charging the battery to running the lights, ignition, and other electronics. … Any of these problems (and more) can be symptoms of a bad or failing snowmobile stator.

How do I know if my stator or voltage regulator is bad?

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 do I know if my snowmobile voltage regulator is bad?

A bad voltage regulator will blow bulbs or cause them to go from dim to bright and back again frequently. The voltage regulator doesn’t play into the spark – that comes from the stator.

What causes a stator to burn out?

A bad diode in a rectifier will dump AC current into a system. The AC current heats up the stator and the heat destroys the insulation and ultimately carbonizes it turning it into a low resistance brick.

Why do Harley stators fail?

Stator Failure:



The insulation on the wires can wear down over time or a wire can break. If the copper inside the insulation rubs against the flywheel as an example, you could have the windings short to ground. This is a problem because it all loops back to the regulator through your battery negative connection.

How do you test a stator on a snowmobile?

Put your multimeter to AC Volts and start you vehicle. As with the Ohms test, test between each lead of the connector (1-2, 2-3, 3-1) and note the readings. They should all be the same (E.g. 20v/20v/20v). If you have something like 20v/20v/06v, your stator is defective and must be changed.

How many volts should a snowmobile stator put out?

Registered. Your stator produces AC, somewhere between 24 and 30 volts. The voltage regulator will pass on somewhere between 13 and 14 DC Volts to charge your battery. The AC current is passed on to your spark plugs.

Why does my snowmobile have no spark?

Disconnect the main electrical connector coming out of the engine, and then check for spark again. This unhooks the kill switch, ignition switch and wiring for those switches. If the spark improves, the problem is within wiring from one of those switches or a switch itself is to blame.

Can a bad stator cause backfire?

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. Runs good at lower rpms but runs bad at higher rpms (High speed coil is going bad) Backfiring and just won’t run good.
