Ronayers.com Fiche Desktop Motorcycle Honda 2000 CBR900RR But be aware that Ron Ayres list all 929 and 954 parts in the same fiches even though they're not interchangeable. The coils of the stator can either fail open, meaning the wire is physically broken and disconnected, or closed, where the wire shorts through it's insulation to a neighboring loop of wire, or to the metal core of the stator, mounting bolt, or engine. In my experience with my 1987 200 HP Johnson, when one of the power packs went bad, all 3 of those cylinders on the port side went out. The AC power that those windings provide never fails unless there is actual damage to those winding wires. So, now that we know some of the differences and similarities in different year/model stators let me list many of the common symptoms of a stator that has gone bad or is going bad: Hard starting: Hard starting when cold or won’t start when cold. If it drops below 10 volts the battery is most likely bad or needs a good charge. Some stators have 1 ignition coil and some have 2 ignition coils which include a high speed and low speed ignition coil. Motorcycle Bad Stator Cause. Even a small scratch in the insulation can be enough to quickly cause a short in the windings as the wire heats up from use. stator Just replaced the stator in my 07 M1000. A failure of the rectifier function in the voltage regulator (also a part of the motorcycle charging system) can also cause high heat buildup in the windings, by preventing the stator's power from being consumed by the motorcycle's electrical system. Yes, ignition components can fail when hot; if that is the case, a spark test while it's failing should show no spark.......or a very weak one. Is a stator a common issue with this motor? And an AC voltmeter to see if all three yellow wires are sending similar voltage to RR. Crack the throttle and it would rev to about 4800 rpm, just enough to keep it moving. I'd suggest testing the stator for shorts to ground, bad resistance between phases, and output voltage at cruising RPM first. While you are down there, clean and snug the connections to the battery. How to Know if Your Regulator Rectifier Is Bad: Symptoms and Solutions . If a stator on a 2000 Yamaha ox66 200hp was bad what would the symptoms be on the motors performance?

Any one of these can mean something in your charging system is broken. Number one cause of stator, voltage regulator failures is a bad battery. Spark plugs keep getting richer/darker as the day goes on indicating weakening spark. No spark. It can be tested using an ohm meter for shorts between wires or to ground. ? Sled slowly loses power during the course of the day. It’s important to note what kind of engine you are working on. symptoms of a bad stator? Insert each probe into a stator socket. If the battery was good under load test, if the stator is NOT shorted to ground, and the stator is putting out A/C voltage, then the regulator is bad (most likely even if if passed step 2). Burned stator my symptoms xt225 250 buell forum stator bad stator fix don t a new motorcycle stator and alternator. Again, when a CDI box is about to go bad, it can lead to misfires, issues with starting, rough running or even stall the motor. Maybe this is a simple problem. Bad stator symtoms ? It is also extremely important to ALWAYS use threadlocker on the stator mounting bolts, since the vibrations from the motorcycle's engine can cause them to back out of their threads, quickly destroying the stator and flywheel. Then would go into stuter mode. 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. Here’s where things get tricky. Runs bad at lower rpms but runs good at higher rpms (Low speed coil going bad), Runs good at lower rpms but runs bad at higher rpms (High speed coil is going bad). There are also windings for the lighting side of the stator. Technically there are 3 possible tests you can do on a stator. Motorcycle Stator Going Bad Symptoms. These mentioned symptoms can be confusing and one has to be careful before concluding that the problem is with the CDI. Switch the multimeter to OHMS range on the lowest setting, usually 10 ohms.

After it warmed up it won’t start but if it sits for an hour it’ll start again. This can be caused by several other problems, however, so the only way to be sure that your stator has gone bad is to perform a series of tests using a multimeter. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. 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. Stator: If your motorcycle is not charging, you need to check the stator. A motorcycle engine that runs hot should be fixed as soon as possible. Generally, motorcycles feature a three-component system containing three wires that link the stator to the regulator rectifier. One of the most common questions I’m asked is: “How does the engine act when the stator is going bad?” First of all let’s understand that most older (2000 and older) batteryless EFI ignition systems and carburetor engines have similar stators and can have similar symptoms. The other common stator failure is from physical damage to the wire windings, either by damaging the insulation or the copper wire itself. Motorcycle won't start. Either type of failure will result in a bad stator that needs to be replaced. "AND NO CODES" Ohmd the stator and found #1 charge coil bad(4.7 ohms). An old or failing ignition pickup may cut out signal intermittently, which may cause the engine to stall. Motorcycle stator failures have many causes, though they always have one thing in common: the coil windings. and a clutch question so I've got my winter rebuild done, and ive been on 3 rides since then on a brand new battery, and its already half dead. Some stators have 1 ignition coil and some have 2 ignition coils which include a high speed and low speed ignition coil. Getting access to the yellow AC wires is pretty easy on the 950.
