Google this text "The quantity adjuster is an electro magnet which moves a piston. It is driven by a pulse width modulated signal so would should on your scope as a square wave which varies in width with RPM
The movement sender is a potentiometer whose value changes as the piston moves. The output of this should be a voltage which varies as the quantity adjuster is moved. "
I have been looking for this info, the two spools (black and white) should have the same resistans. (The black one is blown in mine, Zexel pump, look the same, but kabels coming in on the other side).
The spools are in serie, and are feeded with some voltage....
If we start at left, on the spools, 1, 2 is commond and 3
(One guy told me it's feeded with AC)
I'm working on a Hyundai, but no info on the web, but VW TDI is simular.
Do you have any contact so we can talk about this?

In one document it looks like ther is feeded 2,5 Volt on pin 1 and 3
Not able to send links here....;-(

Great, so it's AC volt controlled the actuator spool?
