Looking for some help on a tach that person has for sale . Its chrome case 9 k rpm tach & inside has E-357 stamped on it in ink claims he bought in 1966 for $60 at a Ford dealer. I take it it must be an over the counter tach . Second question what would it be worth to purchase he claims it works fine?
Any help would be appreciated

First off you would need to confirm what face , what needle and confirm what wires in back . The price will vary by hundreds of dollars depending on what you are looking at.
Face has the cobra logo thin red needle red black wiring , has E375 in ink on inside & has chrome case.
Also did Sun Tach company make these for Ford to sell over the counter back in the 60`s ?

No it was not a Sun tach version. It was a Faria tach version. There are a couple of different locations for Cobra logos. At the very least your missing a wire and a needle based on what you say. There are a number of different types with different details all with different values. I know I couldn't put a accurate value on a Factory Cobra tach based on the limited info given here . Maybe someone else can. ::)
Remember, pictures can help the expert dudes figure it out for you.
All the best,

Sorry there is a white needle & red plus the wire for the light , the being the RPM set needle has a chrome case with mounting bracket.
Chrome cover = Over The Counter. "Bottom logo" tachs ( like the OTC parts) should be carefully compared to a 'known" assembly line tach as Faria changed some of the needles over the time they were manufactured. The bracket supplied with the OTC tachs in not like the SAI version.
Randy
Ya he said he bought at a Ford dealer in `66 . So it would be an over the counter Ford part He was asking $300 (chrome is excellent )
Well with the further detail, it sounds like a Real Mc Coy, and I'd say a fair price. I've seen several 9000 tachs for much more than 300
If it is the service tach, it will not command as much money as the assembly line version. If the needles are tapered, it is definitely service part. If the needles are uniform in width, it is an assembly line tach. They did sell assembly line tach's over the counter. It is only a matter of timing and what was on their shelf when your tach was purchased. It could be either. Tach cups can be swapped out or painted. So the finish on the cup is not a primed indicator of service part or assembly line part, but a chrome one does suggest service part. The needle shapes are a pretty good indicator.
Best of luck

Needles look uniform but are pointed at the end . I would say its an over the counter part from Ford as the seller said he bought from a Ford dealer in 1966 .
Hi Shelby001,
An "over the counter" (OTC) part still can be a configured assembly line part. The description of the needles sounds like a configured assembly line part. I purchased years ago a early NOS COBRA tach with COBRA emblem on top with a August 1965 date code. It had the uniform needle with the chrome cup. I have since swapped on an original wrinkle painted black cup. Now it matches an assembly line tach exactly. The $300 is not a bad price. How are the wires and connectors?
Best of luck.
Cory
Can you post some pics? That will really help to nail it down...

If you haven't bought it then buy it . :o From the info you have added to this thread it is well worth the 300.00 . Then you can post pictures.
Bought it it has been shipped
Thanks for every ones help
Bought it has been shipped
Bought & just received it its Faira June 1966 looks like someone took the face ring off to tangs are missing that hold the face on. Need to test it . any ideas of giving it a quick bench test?
The circuitry is in line or series with the ignition. Install from beneath the dash and fire the engine up and see what happens. If the original wire ends are in place, there is only one way to hook up. If the tach is bad, there is a good chance the engine won't start.
On the bezel ring, you will need to find a none OEM Faria tach with a nice bezel to salvage. The salvage tach should be from the same time period.
Best of luck
Cory
I thoughtof just running the red to the ign terminal on the coil & black to the (-) ground on the battery & firing up the engine. Blue wire is the light.
A parallel circuit is not the same as series. Your're not getting the full resistance of ignition circuit and the amperage could fry the tach. Remember Ohm's law. Current (amps) equals voltage / resistance. Give it a try and let us know how well it works.
Good luck.
Cory
So your saying it should only be hooked up ro the ignition switch?

That is NOT the correct way to wire it! It does go in series. The "plug in " point is the connection between the solid red wire out of the switch and the [pink/salmon colored resistor wire that goes to the coil. That is why actual assembly line tachs had molded plugs on the wire ends to prevent wiring them backwards. These tachs are flow meters NOT rev counters.

Thanks for all the info . Just one question is there no GROUND to the tach as both wire connect to positive?

No ground. I like what Randy said, it is a flow meter. Does your tach have the original male and female connectors. If so, piece of cake to hook up.
Cory
"Technically" it's a "case ground" , not a "wire ground" , and only necessary for the light.
Thats what I was thinking so if these mounted on the dash which was not metal that meant the screws going through the dash pad into the metal acted as the ground?
No there was no plug- ins on the wire ends, matter of fact the wires were cut right at the case ends.
Again Thanks for all the input from everyone.
Hi Shelby001,
Yes on the ground for the light, but not needed for verifying tach function. With the cut wires, you are going to need to get with Phil Severance in Twin Falls Idaho. He does an excellent job of rewiring and restore these old tachs. I have a nice bezel too if needed when you have restored. See Phil's website:

Cory
This is sounding more like a "replaced" tach by the over the counter one. Especially since the wires were cut so short and there is a tab missing. Sending it to Phil is a wise move.
Randy
Phil where is e located ?
Thanks
This thread would be much more informative with pictures from the original poster.
Jon
Google Phidon restorations.
He is in Idaho and the best. Not only do they work but the finish is great. He has done 3 for me.
All the best,
Steve
No not a replaced tach as the owner stated he bought it in 1966 for $60 & installed it in his fairlane. He has since taken a turn to the dark side he has quite a few chevy`s & sold a GT Mustang but has a bunch of parts . He claims the tach was working when he removed it but we will see.

Thanks Steve found his sight this morning .
Good to hear! I bought one that was bad but the seller posted it as ''not tested" , but worked when taken out. A new meter ( $$$) fixed it.
Ya I now have time to get back to testing this tach. I have tested the light & plan on using the wifes 65 Mustang as the test station by removing the coil Batt (+) terminal hooking the black from the tach to the coil & the red wire to wire that i removed from the coil. If the car does not start the tach is defective.
Okay I tested the tach & everything works fine, just need to order a face ring from Phil . Thanks for all help.
