Guest Ignitor Posted August 28, 2015 Share Posted August 28, 2015 Anyone know the polarity of the 8 magnets in the rotor sleeve. I pulled it apart and the magnets jumped together and I don't know how they go in. All North poles out.....? All south poles out.....North South North South North South.. Pertronix technician didn't even know. If you know this you get bragging rights over Pertronix engineers. There are 8 magnets. Each magnet has a north and south pole. I think the Hall Effect is in play here. I have no idea what it does. Link to comment Share on other sites More sharing options...

There are two basic types of digital Hall effect sensor, Bipolar and Unipolar. Bipolar sensors require a positive magnetic field (south pole) to operate them and a negative field (north pole) to release them while unipolar sensors require only a single magnetic south pole to both operate and release them as they move in and out of the magnetic field. http://www.electronics-tutorials.ws/electromagnetism/hall-effect.html Edited August 28, 2015 by joe_padavano (see edit history) Link to comment Share on other sites More sharing options...
Bhigdog Posted August 29, 2015 Share Posted August 29, 2015 The question in my mind is how do you tell the polarity. It would be easy enough to float the magnet in a cup of water and see which end points north. Does the north end point towards the Earth's magnetic north? Or is it repelled by magnetic north thus making the south pole of the magnet point north? Just askin?...........Bob Link to comment Share on other sites More sharing options...
edinmass Posted August 29, 2015 Share Posted August 29, 2015 I made my own reluctor for a Stutz custom job. I put them in all north and it didn't work. Got more magnets and did them all south and it worked fine. I don't remember how I figured out the north or south, but it was not difficult.

Guest Ignitor Posted August 30, 2015 Share Posted August 30, 2015 good info Joe. I was looking for part specific info rather than how you found the all south poles Link to comment Share on other sites More sharing options...
Guest Ignitor Posted August 30, 2015 Share Posted August 30, 2015 edin,So you can make a reluctor with magnets?.....Along with a Hall effectOr did you use another method Link to comment Share on other sites More sharing options...
Guest Ignitor Posted August 30, 2015 Share Posted August 30, 2015 I bench tested my igniter pick up. It's fried. Took it apart to see what's in it.Breadboard with resistor hall ic chip with two prongs and another diode or something but only a total of three cheap peices, two of which I could get at radio shack. The ic chip I don't know if radio shack has that Link to comment Share on other sites More sharing options...
