Tacho Output

[shmed]

I checked my wiring, and the tacho output wire is connected to the main car loom. I'm not sure where it goes to, but I wondered, can I tap into that wire and take it to my external data logger without having an adverse effect on whatever else it might be connected to?

That should be fine.

So, the tacho output still isn't working and I was wondering, can the tacho output be tested using the 'Output Testing' function when the engine is off?

I figured (and I could be wrong) that when I go into the Output Testing menu and locate the PWM output tests, it shows me 8 outputs. My tacho is supposed to feed from PWM-06, so I simply changed the value of box 6 to try and generate a wave for my scope. I don't appear to be able to get a good reading, so either 1. My 'scope isn't working (or I don't know how to use my 'scope - either being possible), or 2. I am not using the Syvecs right, and have misunderstood the 'Output Testing' function.

Can anyone help please? I have totally removed the external data logger from the problem for the time being, and have a new 1k resistor between a 12v source and the Tacho output wire.

Did you enable output testing before trying to test the specific output ?

And the outputs dont pulse as you'd like them to when you turn them on, it's either off/on unless you hold +/- then they pulse whilst you count up or down with the button pressed.

Base states is just either off or on as selected.
