To cancel the noise (shaky tach) you need to put a resistor ( don't remember the OHM right now) inline on your ground wire.

on the ground to the tach, not the sender wire?

Okay I found the shaky gauge answer. A diode needs to be connected to the signal lead if you have points of pertonox type ignition. So the signal wire that goes from the coil to the back of the tach needs this diode. The diode is #1n4005 from radio shack or other supplier it needs to go with the silver band towards the tach in the wire. Hopefully that works, I will try it tommorrow and let you know.

The diode worked wonders, it smoothed it out, and now the tach says I actually do redline close to 4000 rpm which is good.

I'll probably have to pick up one of those myself, thanks.

I've used one of these multi digital guages in the past, they have the advantage of memory so you can always see what was your highest temp.
They come in black too. |
