Jerry, The proper setup is to run a single reluctor and two pickups. What
Lynn and I were talking about was running two complete low cost ignition modules. Think of it like running two linked single rotor engines with
a common e-shaft! If one module failed you could still have one rotor
firing. Bill Jepson
I think you need to define reluctor Bill. Also a sketch would help. I think Jerry is also talking about a single rotor engine.
Paul Lamar ...No rotor no motor.
Paul,
Sorry if I missed the single rotor part. The reluctor we were refering
to is a ferous metal object used to swing through the magnetic field of
a combined magnet and hall effect sensor/timing pickup. The pickup I
was talking about is the one used on early mopar electronic ignitions.
The old EI's in early '70s dodges for example. Best described as crude
but effective, they had a permanent magnet and a fine wire coil that
would be excited by any magnetic material passing closely through the
field. The ignitions were used on V8s using a single coil/pickup with
an 8 spike reluctor. Just a electronic replacement for points. These
units were as far as I can tell totally bulletproof. The only problem
they had was the balast resistor used for the coils (step down to 9
volts I believe) would burn out. I never saw a blown box or pickup
coil, unless caused by mechanical failure of another part. Please
excuse me if I have used the wrong electronic term for the device,
(reluctor) but that is what they have always been called by Dodge.

The hot tip is the Ford EDIS system used on many cars. It defaults to 10 degrees
advance so the dual trigger wheels needs to have an additional 13 degrees
and be slotted so it can be adjusted.
