Pertronix - Hall Effect Vs Lobe Sensor what is the difference?

[patch697]

A mate just fitted the pertronix ignitor 2 hall effect along with the flamethrower2 coil (45,000 volts, 0.6 ohms resistance). He reckons it drives way better. I'm just about to order one for me. Check out rusty nails diy thread, he shows how he fitted a pertronix ignitor 1. Lobe sensing (while keeping the factory coil).
The points are removed for the lobe sensing version. I think it uses a magnet to sense everytime the lobes go past (instead of the lobes mechanicaly moving the points open). The hall effect one uses a magnetic ring that slides over the lobes and gives a better signal to the module. The only reason you need to machine the shaft is so the magnetic ring fits over the little step that the rotor button sits on...

Tap, crackle, pop

Just to add a bit to the above quoted post, its dead easy to remove & refit the top shaft that needs the step knocked off from the distributor without removing the entire dizzy. no more skill is required than whats needed to fit the Pertornix in the first place.

I took mine into the local machine shop & they machined it off for under $20 clams.... Problem solved.

Yeah we had the dissy out anyway. They put it in a vice, a drill on one end to turn the shaft, and a file to machine it down:-)

Did you remove the shaft or just did the machining of the shaft in the distributor????

Patch he means he gripped the shaft of the dissy in the chunk of his drill while the whole thing was out and then just pulled the trigger and filed it down, kinda like a low rpm makeshift lathe.

In Rusty Nails thread I added the extra steps you need to take to fit the Pertronix 2 with some photos, but if you follow pretty much exactly what I wrote earlier in this thread you shouldn't have any dramas. If your in Melbourne I can do it with you if you'd like.

Whats confusing the hell out of me, is in the ebay description at one point it says lobe sensing, then further down the page it make reference to the magnets creating the hall effect....

Arrived yesterday nothing like the picture in the bay auction, as mentioned above, was supprised that no magnetic ring was packaged, after reading the instruction, said this model didnt need it, so wired it up, and it started.. was not impressed with the flame thrower coil as it didnt come with its own mounting bracket, and being almost half the size of the coil that was in it, which looked like more than likley the origional coil, had to modify existing coil holer to hold the new coil in place, cant say I'm impressed with it yet, was near dark by the time i installed it. so havent done the timing on it yet, will see if that makes a difference, have read on here to set it to 12 degrees BTDC, will update after that...
but so far ... FAR from what their sales pitch says
Delivers twice the voltage to the spark plugs, increasing horsepower, fuel economy, and spark plug life.
2:1 improvement over points in current fall time for increased coil output.
Rotating cobalt magnets trigger a Hall Effect integrated circuit . ...no points to burn, ...no moving parts to wear out.
System is designed for use with most point-type coils, optimal performance achieved when used with our Flame-Thrower® 40,000 volt coil.
Works great in stock point-type distributors as a trigger for multi-spark CD ignitions, eliminating the need for expensive aftermarket distributors.
No complicated wiring makes installation easy.
A solid-state electronic ignition system. "Never change points again!"
Epoxy molding makes our module impervious to dirt, oil, grease and moisture.
Fits entirely inside the distributor.
No "black box to clutter the engine compartment.
Stable timing ...no need for any adjustments.
Will trigger most multi-spark CD ignitions.
Use with Flame-Thrower® 40,000 volt coil for optimal performance.

Although I left positive feedback on ebay, but commented on it looking nothing like the picture, the guy is refusing to give me any feedback, and has pretty much told me, if something goes wrong with it, tuff luck.... real nice guy....

[Irvs]

Yeah mate as said the eBay picture is a generic one and you got did end up getting the right one anyway, I just wedged some cardboard in between my coil holder and coil, still haven't gotten around to fixing it yet, might do it soon, haha

Std coil is larger proberly holds more oil for better cooling.
may not be impressed now.
you will be impressed not having to play with points every other month.

Hi folks,

I'm also looking for a Petronix for my 4.2 Carby, but now I am kind of confused...
I checked the Petronix catalog and found a Patrol on top of page 15.

For distributor make Hitachi - Ignitor 1763LS - Ignitor II 91763LS

On page 21 I found the 1762

For distributor make Mitsubishi TOT 00471 - Ignitor 1762LS
..........TOT 00471, 22100 03510 (Nissan) - Ignitor 1762 - Ignitor II 91762

Now which one is the right one???
As my Patrol is still in Namibia and I am buried in Germany there is no big chance to have a closer look at the Dissy...

Cheers
