Many distributors used in electronic ignition systems contain internal components and layouts
the same as the distributor described above, but are fitted with mechanical and/or vacuum
advance mechanisms which are much less effective and flexible than electronic timing as in
the E6K. If these mechanisms can be defeated or removed, and the timing edges set correctly,
then they can successfully be used to trigger the E6K.
A third type of pickup, the magnetic inductive (reluctor), is used in distributors as well as on
crank trigger units. It is possible to use this type of trigger on the E6K using it’s own internal
reluctor adapter to convert the signal into the square wave required to trigger the E6K. The
Primary input is used for the main trigger, and the secondary is used for the Home(Sync.
Event) or Road Speed input.(See Syncronising Events, Appendix B2.2, B3.3 and E.3).
Note: Any combination of hall effect, optical or reluctor type pick-up may be
used for the “trigger” (main ignition event) and “home” (sync. Event) inputs.
However, reluctor type pick-ups must be connected to their respective reluctor
adaptor input.
The onboard reluctor adaptor actually has two independant channels. One is
for the “trigger” signal. The second is for the “home” signal.
Each reluctor adaptor channel used requires two wire connections.
The magnetic pickup is basically a piece of wire wrapped around a magnetic core and
attached to the sensor face, which is called the pole piece. The physical size and shape of such
a pickup can take many forms. This type of pickup has either two wires (one positive (+), and
the other negative (-)), or three wires with the third being a shield. The wires are sometimes
marked as such, but more often than not they are unmarked.
Note: If using a “reluctor” type for the TRIGGER signal input:
The Positive pin from the “Trigger” reluctor pick-up connects to the input of
the onboard reluctor adaptor (PIN B (TRIGGER), on the Trigger Input plug).
The Negative pin from the “Trigger” reluctor pick-up must connect to the
negative reluctor adaptor input (PIN D (INPUT B), on the Trigger Input plug).
If using a “reluctor” type for the HOME signal input:
The Positive pin from the “Home” reluctor pick-up must connect to the input
of the onboard “HOME” reluctor adaptor (PIN E (HOME), on the Trigger
Input plug).
The Negative pin from the “HOME” reluctor pick-up must connected to the
negative “HOME” reluctor adaptor input (PIN C (INPUT A), on the Trigger
Input plug).
Note: If a motronic trigger is being used refer to section E.2.2 Motronic
Trigger as the wiring has some variation.
If you cannot tell which wire is the positive from markings or wire colour, then it would be
necessary to check the signal going into the E6K using an oscilloscope.
When ferrous metal (metal that a magnet will attract) is passed very close to the pole piece,
the pickup will generate a voltage similar to figure E.5a on the positive wire. The amplitude
