? 1. 3. It is often the case that the old switchbox(s) fail shortly after a new stator has been installed. My rectifier is bad and it will take around 20 days to reach or ao. Outboard Spares Response Hi, sounds like it could be fuel or ignition timing. And How to Make Them Last Longer! In order to perform this test. 3. Turn the engine off and swap the stator leads. 2. To perform the Voltage Output Test you will need a special DVA Meter. This means that with lower output stators, the charge output through the regulator / rectifier at idle or low rpm is very minimal. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. This is because a bad stator can weaken or ruin a good switchbox. So it all depends on your engine and what kind of system it uses! Bad voltage regulator symptoms outboard Bad voltage regulator symptoms outboard Will An Outboard Run With A Bad Stator? Your outboard stator is the "powerhouse" of your outboards ignition system. Most Mercury Outboard Stators perform two important functions Maintenance on these engines is relatively straightforward, and many of them sit for an entire off-season without being started. And you can also donate by clicking the donate button here or on the right hand of the screen! It too has two coils, high speed and low speed. Jerry C. 2. No, other smaller outboards will not run with a bad stator. The stator plays two roles. If there is no voltage increase, either your stator or rectifier is faulty. Aaron has been working in the Marine Industry for over a decade and holds certifications for Yamaha and Mercury Marine. As you increase the rpms to 1500 -2000, the voltage should rise to about 14 - 14.5 volts. 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. A stator can be easily tested with a digital multimeter. It will not even start and run if the stator has failed! This solution completely bypasses the stator by using a 12 volt battery to power the ignition system. I was wondering if I could run (short runs, of about 20 min go and 20min back) without the rectifier, by unhooking it to the stator and from the wire that goes to the battery. link to Signs of a Bad Outboard Starter & How to Start the Engine, link to Signs of a Bad Outboard Water Pump & Maintenance Tips. We create all kinds of how-to and DIY videos. No, other smaller outboards will not run with a bad stator. They charge your vessel's battery(s). No spark. A stator is a component on an engine that is attached under the flywheel of the engine. Evinrude angler 5hp Not rated yet Runs great for about 30 minutes then loses power till it won't run any longer.let it set for about an hour and it will run and repeat the problem. For the low cost of a new rectifier, it doesn’t make sense to operate the outboard without it. Stator resistance ranges vary from motor to motor. Ok you have either the engine is running to cool or the temp sensor is bad. Thanks for reading and we look forward to reading your responses and comments. Diagnosed with ohmmeter reading as well. I am totally lost. what model engine you have. When the stator goes bad, your ATV will only run until the battery goes dead, which is not very long. To perform the Ohms Test you will need a good ohm meter. ... Bad stator symtoms ?

As the magnets on the flywheel spin around the windings when the engine is running.eval(ez_write_tag([[728,90],'bornagainboating_com-medrectangle-3','ezslot_10',106,'0','0'])); This AC electricity is used by the engine to run all of the ignition components of the engine. 1. Then disconnect it. Got to run out for a bit be back on in a couple of hours. Everything required can be purchased for under $50. Engine is hard to start especially after sitting from a run. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Check Us Out!eval(ez_write_tag([[300,250],'bornagainboating_com-large-mobile-banner-1','ezslot_17',111,'0','0'])); Now that you know all about outboard stators and how to test them. Good luck, post back on what you … Engine is low on power or has a "miss". Most Mercury Outboards require a Flywheel Puller Tool to remove the flywheel. One set of the coils on the stator feeds the … A bad stator can have all kinds of funny, hard to trace symptoms. As we said earlier. The typical windings in a coil assembly include:--high current winding for battery charger output, usually about 10 to 15 … If you’ve got any questions or comments, let us know by subscribing to our YouTube Channel!eval(ez_write_tag([[300,250],'bornagainboating_com-large-mobile-banner-2','ezslot_18',112,'0','0'])); And if you would like to support us to continue bringing you great content, please click the link below to Amazon where we get a commission from anything you are already going to buy! So I replaced it about a week ago. Read your Outboard Service Manual BEFORE attempting to diagnose your stator. They provide voltage to your switchbox or CDM's. I believe that the coil assembly in a Mercury outboard contains several windings. 4. There are some larger engines that will run with a partially bad stator. Overcharging. symptoms of a bad stator? 3. Ground connections are important for good voltage, and if there is faulty voltage, the regulator rectifier can run hot.
