is this what the inside of the RAD flywheel is supposed to look like?

PS: Terry, your take on this Hall Effect on the SXR debate? :biggthumpup:

Yeah, yeah, can't take Jersey out of interweb:biggrin:

What is hall effect. I've talk in length to Greg at Advent, & Dan at Jetworld about SXR electric and never once heard that term:phone:

The trigger pickup, in Electrical Engineering terms, is a Hall Effect sensor (because of the way it works).

Can't take the EE out of Matt_E. :biggrin:
We'll call it a trigger pickup to avoid confusion, sorry.

In short: a wire with current going through it will generate a small voltage at a certain phase angle when a magnetic field comes across the wire.
Compared to the older coil setup, the H-E sensor is much smaller, lighter, requires a much smaller trigger magnet, and has much less drag on the rotating mass of the flywheel. It is also more accurate in precise timing and less prone to noise.
It is ideal for feeding digital ignitions because of fast response and small, precise signal (square wave, essentially)
Nearly all modern ignitions use it (not just PWC ignitions)

Sure. A hall effect sensor also puts out a signal roughly 0-1VAC and has two wires.

The SXR uses a digital DC-CDI (see specs on Kawi's website if you don't believe me).
As such, it wouldn't use the older pulser coil setup.

If you still don't believe me, check out the parts microfiche, section "Generator", and look at the small rectangular box coming off the stator leads.
That is the Hall effect sensor.
The coils on the stator itself are lighting and charging coils.
You will find identical setups on the Yamaha ignitions (760/800/1200/1300)

You're wrong on the SX-R using a pulser coil. Not trying to give you a hard time, please don't misunderstand me.
Btw, this applies to all years of the SX-R.


And if you want another angle to look at it, if it were indeed a pulser coil setup, the ignition would cease to work once you knock all the magnets (sans lobe) off the flywheel.

Ok Matt since you obviously don't know how an AC generator works I am going to tell you .An AC generator is a magnet with a coil of wire wrapped around it as the lump on the flywheel which BTW does not contain it own magnet passes the Pickup-AC generator it produces a small current which triggers the ignition to fire. I know what a hall effect sensor looks like and I know what and a AC generator looks like .Both the Kawi and the Yamaha use AC generators -pulse coils to trigger the ignition to fire,stop telling me to research this and research that ,I have been for the last twenty years,now run along and go read some more on the internet.:chairshot:

lol.... you guys are arguing the same things, while explaining it in different "terms" your being confused on what the other one is saying, and taking the responses as contrary. matt is right about the digital vs. analog setups, "hall effect" sensors are there terry, they're just configured differently in the circuit i/e year model, although producing the same results. I don't even want to bring up the subject of "proximity detection" for known reasons...lol, but that's basically what it is, digital and/or analog. without that being the case, the ignition wouldn't "know" when to fire the plugs. pulse coils are pulse coils, they're just configured differently, i/e again, year models. they changed the configuration based on efficiency and a more smooth and concise control of ignition at varying rpms.

By all means bring it up Travis, this thread was fawked up long ago,but you are correct on one point AC generators and hall effect sensors do do the same thing but in a different way.The difference being that an AC generator contains both the magnet and the coil and is actuated by the lump on the flywheel which creates a magnetic field when it goes by the AC generator ,a hall effect sensor does not have its own magnet and it is actuated when a magnet comes in close proximity to it creating a magnetic field. There are so many things wrong with Matt said I don't even know where to start, doesn't matter as he believes he is correct and you won't convince him otherwise.I believe I said earlier that we could argue the semantics of this for about a week,this is the second day so 5 days left to go I guess carry on :highhorse:

they are just two converse forms of "hall effect" sensing. they are just configured differently, producing the same effect. when a magnet passes a coil, and the coil "senses it's presence" " getting near it" and/or "going by it" generating a signal, it is a "hall effect", same thing goes for the AC setup while basically the "lobe" is the on/off switch actuator by proximity of the wheel, same effect. especially prevalent when concerning the proximity detection for a specifically timed released CDI coil discharge to the plugs in engine timing. usually when "hall effect sensors" are not used, it easier and less confusing to refer to what's taking place as "proximity detection" although, it is, in effect "hall effect"...lol

But the man came to a river he had to cross with a chicken ,a bucket off feed and a fox,he could only tote two across at a time on a small boat,how did he get all three across without the Fox eating the chicken or the chicken eating the feed? Think on it a while and ge t back to me ,I know the answer.
