Tachometer for my model A

I recently bought and returned an electronic voltmeter from Harbor Freight that was supposed to be able to register engine RPM. Supposedly, either from clipping the probe to the coil or using the coil wire pick-up. It did not work. It just registered random numbers on the display. I took it back and claimed it was defective. They graciously exchanged it. The second one did the same thing, so I took it back and did not ask for another one.

I don't know why it would not work, but perhaps because it needed 12-volt power instead of 6-volt.

Too much noise from the unshielded ignition system for digital meters, especially inexpensive ones, to work. This is why analog meters with a needle are recommended for the Model A.

Unless there's some reason you want 12 volt, this place sells 6 volt, + ground, 4 cyl tachs for $125

Yes Y-Blockhead your right. Here is the web address.
www.westach.com The tac shown in post 13 is not the same one I have.
 
Bill Jones has a SMALL LED, rectangular tach, that sticks on his dash rail. It has its' OWN battery & I "think", a skinny wire, that just winds around the coil wire. You notice,I use a LOTS of QUOTATION MARKS, when I'm NOT SURE of stuff--LOL---Wouldn't EVER mean to MIS-LEAD someone.
Not "SURE" of the BRAND name???---MOSTLY, I just recommend stuff that has worked for me, PERSONALLY, in my SORID MECHANICAL BACKGROUND. "Sometimes" something I lurned while workin' on a GOGOMOBILE, "might" apply to a Model A.

The Westech 6-volt model 2CT32-6V looks interesting. Could some of you who have installed this device post some descriptions on how you mounted it and hooked it up eclectically in a Model A.

Not trying to be critical or funny, but why would I want a tach in a Model A? I have one in my Mustang Cobra, which does redline at 7,000...been there many times in fact. But the Model A just does not make sense to push and the actual RPMs do not seem important. Is this a curiousity being satisfied?
