I'm building a programmable ignition module. It gave me 6 options to use for the sense signal from the engine. Points, hall, reluctor etc. I had a spare unknown metro electronic dizzy - I decided pull it apart and it's a coil around a magnetic centre with 4 points that spin Around it with another 4 points that are fixed to the vacuum advance system. Is this a reluctor??? Or have I been really fucking stupid and made the mother off all assumptions - a wrong one?!

So assuming I'm correct (there it is again) and it us a reluctor, shouldn't the coil of wire be continuous giving continuity when checked? I checked the coil and it's open circuit, so I'm thinking that's the bit that's causing my headache...

The dizzy is 65dm4 type with module attatched...

I'm not actually using the module on the side of the electronic dizzy. Just straight out from the coil to my ignition module.

I'm afraid the first bit just doesn't make sense...

Who/what is Somi and what dizzy is it, remote module or side attached ???

What is bd ???

If you do a search in the EFI section, someone a while ago tried using the internals of the electronic dizzy by itself (no module) and also failed.

I can't remember why but it's possible the internals need power from the module to work.

But if you have ripped it all apart, why not just fit a Hall switch or Optoswitch in place of the original internals which we know will work as some of us are using Hall switches/Optoswitches in dizzy bodies to drive MegaSquirt phase sequencing quite successfully.....

(EDIT - to make more sense)

The dizzy is the 65dm4 type with the module that is attatched to the distributor

I found A topic on the mini forum with someone stating it's a hall effect - anyone else heard that?
