Tach install help

It works fine, I don't have the number on the sensors since Ive used all of them I had. I buy them usually off of ebay cheap. They are 3 wire proximity sensors, and if you look at specs you can find sensors that will pick up the bolts with a gap up to 1/4 inch. I can usually find them for 15 bucks or so each. You can buy new out of msc but the cheapest I ever found that I thought would work were $60 or more. We use the same setup on pulling lawnmowers with half of a lovejoy coupler on the engines shaft for the pickup. Ive used many different sensors and had great luck with them all.
 
Ok so let me see if this might work or easier for me to understand the hookup?

Using either the Dodge sensor, or say a Ford sensor, (both are magnetic or hall effect right? and I have one of each on hand) and aimed at the balancer bolts, what does it take to hook up the standard three wire tach from there?
Both appear to be two wire sensors

Is there a simple interface between the sender and the tach that can be constructed so they work together?

I really want a 5" recall with shift lite tach which isnt available for a diesel so must adapt a gasser style tach.

Ive never tried, but i would imagine you could use a factory sensor but rewire for 12v to trigger the aftermarket tach instead of the 5v that the sensor is using now. you would have to set your tach to 4 cyl, and wouldnt be able to use the factory in dash tach off of the sensor at the same time. night be worth trying.

That's what I'm using. A 2-wire sensor with one side connected to +12v and the other connected to the tach pickup terminal. As I posted above, this sensor is reading 6 pulses per rev from the torque converter bolts.
 
so u have the tach set for a 6 cyl obviously as there are 6 converter bolts?

So if i wish to do the balancer bolts i would set for 4 cyl?
 
you cannot use the converter bolts with just any tach, you must remember that a gasser only fires the ignition every other revolution so you must actually double the number of pickups you have. 4 pickup points=8cyl 3=6cly 2= 4cyl. to use the converter bolts with a normal gas tach you would have to set it for a 12cyl engine. some new tachs, are set to pulses per revoloution, if you have one of those, (like the stewart warner joefarmer is describing) you will set it to how many notches or bumbs you have, 4 ppr for the 4 crank bolts.

The Auto Meter Diesel Tack #6806 comes with it's own probe.

I have it located on the front of my schielding reading off the four bolts. The magnetic side pick up is for the Corsa Data system.
