Spare time! A luxury I may able to afford in a few years.

I will post ASAP with detail, I try the K.I.S.S way and if I don't get good result I take the hard way with what I have left in stock in my drawers.

The circuit was posted for someone who really likes to tinker.

That's my fricking problem...Too much thinking, not enough doing!:bash2:

One day a friend tell me, those who only take the hard way to resolve a problem got a small di**, since that day I try to find the most simple way to get the job done. :OhOh:

Have to go trying the stupid way first...See ya :Wave:

The simple (stupid) way was not accurate so I decided to crack the belly of the Faria meter.

Here you can see the heart of the beast, a crappy Chinese RPM driver (Frequency to voltage converter) made by Cherry Semiconductor. (CS289-9635J)

Now all I need to do is study this circuit and lower the voltage send to the meter coil, simple enough? We will see :coffee:

Here is a tachometer that is programmable for 1 to 12 cylinders and has Inductive Pick-Up from the coil or spark-plug.

Too bad it is 2.5" in diameter.

Don't worry I all ready figure it out, I'm missing only one small part and everything is close until next Tuesday here. I will post a small video to show the result. :NailBite:

Looks like it will clamp right on the steering column. Might have to purchase that tach.

I wanted to give a quick update. I rigged up the tach I bought off eBay and it has worked. I'll get it setup this weekend and get back with everyone.

Good to know it work :ThumbsUp:

I got the parts I need to mod mine, I just need spare time to give it a try. In the mid time I found Kirk installation pdf file, he take his signal from the ignition coil instead of the stator/generator.
