Speedo Sender ~ Hall Effect Sensor!
Help!!!
I have managed to get hold of a speedo sender from a Vauxhall Nova which converts the rotary motion of the speedo cable to a pulse (i think)
Question.
There are 3 wires coming from it. I assume:-
A Live, an Earth & a Pulse.
Ready for the dumb question.
Does the pulse wire return a voltage? If so is it the same as the input voltage?
Cheers in advance,
The Baron

Hello Baron,
It depends on the type you have but most I have come across drop to 0v when detecting the edge of the target.
