Stator Rewinds Motorcycle Electrics Specialist All motorcycle stators rewound to factory specs or better, including pickup coils Racing specs or high reliability available Standard alternator stator rewinds come with 3 months warranty Ducati electronics are our speciality. The next time you run the car, the alternator will fully recharge the car's battery and replenish the power you took. The stator had performed well under heavy load for an extended period of time prior to the failure so I had no reservations about installing another one like it. For 95 miles everything worked perfectly with the jacket liner keeping me toasty warm and the charging system maintaining approximately 14 Volts. Could be some good info there to add. Have a 56 Fleetwin 7. Electrical Apparatus can provide the high-quality stator service you need at competitive rates! Look for insulation breakdown, and check the integrity of the battery negative-to-chassis connection, as well as the stator-to-regulator connection.
Now for that last wire. Start the engine and turn on all electrical accessories. Capacitor: Any capacitor intended for ignition systems will work. I glued the toggle switch near the original kill switch on the handlebars and wove the wires back down to the other elements. Another location was found where the stator wire made contact with the mounting shoulder. After going though a full cycle in the burn down oven the stator is thensandblasted and alllaminationand stator teeth are repaired and freed of all sharp edges or areas that could, over time, wear though the insulation and damage the coils causing a premature failure.
There are several methods for charging the battery. I was worried it was in motorcycle primary chaincase or something. Disconnect the battery negative cable, and install the meter probes in series between the battery negative post, and negative cable terminal. Look for places where foreign conducting materials might be resting against the terminals of various components. Please e-mail us a picture of your stator at:. You can lock it in place by using a special tool. Sailboat guys crave them for auxilliaries.
I wish to especially thank Dan Topping for his excellent suggestions and comments. You could even use a hybrid approach to power the ignition with the battery and the lights with the stator, but once again you would have to figure it out on your own and rewire the stator after disconnecting it from the ignition. It saves the points so you wont have to change them as often. They sell small ones for use in dirt bike starters, security system back up power supplies, etc. Symptoms are often worsened as the engine warms up. A test fit was then performed. I massaged the windings to encourage wires to separate.
A couple of hours later I decided to troubleshoot the electrical system - surprise, it was charging again. Are a couple of the coils made from much smaller wire, for the ignition? Lastly, a short circuit could cause the failure of the system. If you use a higher voltage charger, the process may go faster, but you face the risk over damaging the battery because it will not stop upon completion. With the wire routed out of the way, put the flywheel back on and replace the side cover. Different Motorcycle Stators There are different kinds of motorcycle stators, as they have changed with the generations and types of motorcycles. Using the voltmeter function of your multimeter in the proper voltage range, attach the leads of the meter to the alligator clips on your power source. The second and much less likely cause of a system failure is an issue with the contact breaker.
If you can pry apart any spotwelds you can fix it. I think it was Minwax brand. I'd cover the armature with something to make a softer bed for your new windings. Suggestions and criticism are welcome. Set your multimeter to check amps on the lowest scale.
Most recent conversion was a friend's '55 Johnson 5. The first dynamic test allows you to check the rotor that contains the magnets and spins around the stator. Use a 2 ohm resistor rated in the neighborhood of 100 watts of power. I prefer to wrap this wire around a bolt and then tighten it. Rick's Motorsport Electrics is another source for stator rewinds.
The stator is the set of copper coils surrounding the crankshaft. Next, a Dremel tool with a carbide burr was used to trim the sharp corners at the four potential contact points. Also, when I rewound the coils, I got them as tight as I could, but the wires didnt wrap as neat tight as they did from the factory. The first is that some stators can be really difficult to rewind and still get a half decent result. Sending us your stator for repair? I did know nothing about stator winding before doing this, but at the end after one failed attempt which short circuit I made it.
Thanks for the reply Jim. It might be also valid for other brands. If you put this wire in the wrong place on the contact breaker, it will directly contact the first wire and bypass the switching effect of the system. Using pry tools is risky, so I recommend using the special universal flywheel tool that I mentioned. Without the switching effect of the contact breaker, the spark will never fire.
