I've searched and cannot find an answer...
I have a motorcycle ecu tach signal that is either 3 or 5V that I can pick up on my multimeter.
However when I try to hook up my Stack tachometer, no readings. It requires a 12V signal.
The Stack tachometer lead should be a high impedence lead that shouldn't draw much current at all.
I have read about transistors and pull up resistors. I think I am a little out of my league wiring up this from scratch.
I found several voltage level shifters (40109 is the one I'm looking at) that seems to do the job for me.
Any suggestions???
Thanks in advance.
