I use a digital speedo on my bike. At the moment I have no readout.

It uses a rare earth magnet, mounted in one of the rotor studs. The pick up is mounted so the magnet runs right past the centre of the receiver thingy.

With the magnet positioned in alignment with the receiver, what/how do I test to see if the receiver is working.

Does the receiver act as a switch? Or send to the speedo a pulse.

It used to work fine ...... I need help with this mystery.

Ah ha. Now I remember why I had two spacers behind the mount, which I don't now. Magnet now runs dead centre of the receiver, and as shown in the diagram, this is not how it works.
Back to the drawing board.

Buggered if I know mate  (dunno)

But I reckon reading the instructions was a good idea.

Chris, Quite often I write things and press the 'post' button.......... but then I realise my self-moderation mechanism has kicked-in again - I am disconnected from the internet...  by the time I reconnect and read what I have written again, I change my mind and delete for many reasons!!  Perhaps you should try this?

One of those moments, you know how it is build it, put it back together after it burns to the ground, and completely forget what those two M8 half nuts were for :-[

It turns out, my magnet has lost a lot of its magical powers. Used a magnetic key hook passing it over the sensor and managed to get to 37kph whilst stationary.

Now I just need another magnet.

So you're already up to the speed when it seized . Progress indeed..
