not figured it out yet, i have now blown the 7805 chip thing so have to buy another 1 or 2

i have no idea how to make this work, fitted a new 7805 and put a multimeter on the output wire and it reads 5v down to 0v when spinning the sensor,
but if i connect it to the acewell 0v side of the connector nothing at all. changed the circumference settings from low to high and in between but
nothing.
This is driving me nuts

I thougth the acewell just works off an looped earth supply with a reed switch making the supply back to the unit when the magnet passes it.
Just checked my and there are deff no voltages on either of the sensor wires.

i have a 3250, i know some differ.
i have now found with my circuit connected to everything apart from the acewell. If i touch the 5v from the acewell on the heatsink on the 7805
(effectively earthing it) i get a reading.
With is in mind i have connected the 5v from acewell to the signal from the 7805 and spin the sender in a drill i find the volts never drop fully to
earth.
My problem seems to be an earth related thing. is there a component that has a constant 5v input that can earth when a voltage is applied to it like a
relay?

I've finally sorted it with the addition of a transistor. just need to calibrate the set-up to make sure of faultless readings but it works in a
drill

final update, had the speedo working up to 80 and it's perfect, cheers for all the help
