Greets Guys and Gals,
I wonder could anyone of you shed some light on the ignition coil and module of a VW Polo 94, maybe somebody has a schematic showing the hall effect sensor.
I have on my table an ignition transformer, it has three wires
GND
In
+
I assume the plus is Battery +
Gnd to be Battery -
But the In, I am lost. I know this is a signal derived from a hall effect sensor but what actually is happening to the input voltage wize.
Is it usually Battery + and the hall effect sensor switch connects it to zero
or
Is it usually zero and the hall effect sensor switch connects it to Battery +
If in its active state, does the transformer generate HV, or does it rely on constant changes of the In signal.

Re: Schematics for Ignition system
In is the trigger pulse coming from ecu.
