tach drive

[FlatRat]

What's the secret to running an elect tach with a mag?I know,rookie question.

You must buy a tach specifically designed to run with a magneto. They usually use an inductive pickup rather than a direct connection.

Flat Rat, Use mech, tach. I run a Vertex mag, but I taped the balancer bolt and ran the tach drive off of it. I think you get a better reading.

Does your Mag. distributor have a mechanical tach drive hookup?
I've seen a little generator type deal that hooks up there and puts out pulses to drive a normal tach. I think Auto Meter made them at one point, not sure now. If you can't find them let me know, I'll as my brother inlaw, he has one on his Dodge...

Flat Rat, I have one that I am not using! Hey, I thought you have a mechanical tach! Drive it off the casale!
