aftermarket tach question
aftermarket tach question
hey, i know this has been covered before but i didn't find any real solutions when i searched, but i definitely could have missed something.
has anyone done a successful aftermarket tach?
im wondering, why couldnt i put in a different alternator and use the w terminal from that to run the tach? most aftermarket tachs seem to run from the alternator. am i missing something?

Autometer and Depoe racing. They both use the alternator for a signal. The Autometer goes on the outside of the alternator. The Depoe racing requires a wire from inside the alternator but it has a shift indicator.

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
It's really not that complicated, but I can't walk you through it because I haven't done it.
The stock trigger is a hall effect sensor. What that means, in a pin on the crank passes a sensor. The output from this is basically a switch that closes once every crank revolution.
So, you need a tach that will take a closing switch as the input signal, and outputs to a needle gauge.

I thought it was a VR sensor. Just 2 wires right? IDK if it would still work, I'm not a tach expert, but it's the difference between a square wave and a sine wave.

It might be something else then, I always thought it was hall effect. Okay maybe I don't know so much :p

Just talked to Dakota digital and they said that this will work on our 5cyl diesels with a gas aftermarket tach. I think I'll order one in the next month or two and see
