yenko guage question
 

I just bought a Yenko guage as it was explained to me. The guage goes from "." - 8000 does not have a "0" but just above the dot or "." it has a small 500. Questions are:
1. Is this guage rare?
2. How much is it worth
3. What year would it be from?
4. Do I need a sender with this guage or can I hook it straight up to the engine and power using the 4 wires it has (red, green, white, and black)?

Re: yenko guage question
 

Can I assume you're referring to a Stewart Warner Tach?

Maybe this model?

That is the late model pedestal and was not available in 68,69, or 70. This earier style(http://cgi.ebay.com/ebaymotors/ws/eB...m=250460972702)
was used on the 68 and 69 Yenkos. This is a shameless plug since it is my auction. Both the tach posted earlier and the tach I just posted require a 990 series monitor.

In fact, now that I look at it the Windex and SS hood in the background on the first picture look familiar. I think they are both my tachs. A double plug I guess.

Re: yenko guage question
 

it says 977 on back looks similar except it reads on the right:
RPM
thousands
SW

see attachment, not sure how to add an image like you did to the post

Guilty! I swiped your photo. https://www.yenko.net/ubbthreads/imag...lins/crazy.gif

Just thought it might help answer his question.

Re: yenko guage question
 

WOW 142 views and only 4 replies and most not on this guage from 2 people in this forum. That tells me that this guage is rare and probably worth a couple hundred dollars since few know much about it. Anyways, It was mentioned that I need a sender unit to make this work. I am not certain but when I took the back cover off there is already electronics there. Why would I need more? doesnt sound right...

Re: yenko guage question
 

Dennis,


I was just poking fun. Swipe all the photos you like https://www.yenko.net/ubbthreads/imag...lins/smile.gif. Darren, Both Dennis and I tried to help but you did not give any more info. Here is a link to some 970 series tach instructions I posted on this site for just this type of situation:

https://www.yenko.net/ubbthreads/showflat...true#Post363743
The tach will work without the monitor for a short time, then it will most likely fry. I have sold those panel mount tachs in that style from $50-$200 on Ebay. It really depends on timing and condition. The $200 one was NOS and was the tach I got those instructions from.

Re: yenko guage question
 

Jason,
I am just getting a little frustrated at how hard it is to find info on these tachs on the web. The tach is not even going into a Camero it is going into my 72 plymouth satellite with electronic ignition (yep I am a mopar guy) I really want to make this one work and do not want to fry it. Thanks for the diagram, looks detailed would all this work on a plymouth satellite with a chrysler 400 (electronic ignition,) or should I send it to one of those people and have them change out the guts in it? expensive...

What's a Camero?

Re: yenko guage question
 

What's a Camero? C'mon now, it's a poor man's Carvette. Everybody knows that!

Re: yenko guage question
 

Yes, it will work in your car. You wll most likely need a SW 990D transmitter. Does the mopar electronic ignition have a "Tach" output like a GM HEI?


Jason

Re: yenko guage question
 

professor james I said Camero sorry I meant to say camarro.

Jason, not sure if it is the same as a gm. I did rewire the whole car with a painless kit. My current cheap tach is tapped off the coil (green) do you have this sender that I need? If so are you selling it? Further what's in this box anyways?

Re: yenko guage question
 

You say potatoe, I say patatoe........you say camarro, I say Camaro.....potatoe, patatoe, camarro, Camaro........let's call the whole thing off!

Let's call the whole thing off

Lol

Re: yenko guage question
 

Yes, I am selling senders. The senders basically have a few resistors inside them. Here is a link to the ad I have in the for sale section:

https://www.yenko.net/ubbthreads/show...e/3#Post407785

As you can see, the senders are as much or more than the dash mount tachs.


Jason

Re: yenko guage question
 

Are there schematics somewhere? Maybe I can build my own..

Re: yenko guage question
 

Hello?

Re: yenko guage question
 

I am done with this thread. I have been trying to help and instead of a thank you I get an impatient "hello?"

Re: yenko guage question
 

Xplantdad you were never part of the thread so it should be easy for you to move on.

Jason you did help a little but I think maybe you had no further interest in helping after you figured out I had little interest and paying $200 on a hunk of crap that I can make for $20 and a trip to Radio Shack. I found a schematic that gave me a little insight to what’s in this little magical box. A couple of capacitors, a relay, a couple of batteries. Its nothing but a protection circuit for the gauge, and your right without it I would fry the gauge. The signal from the coil does nothing more then activate the relay. The batteries run the gauge. What I cannot figure out is why they did not use a 555 timer circuit instead, that’s right they did not invent that yet. Anyways no hard feelings and don't hate me because I am a Mopar guy...

PS I ran spell check just for the professor

Until a couple days ago you were never a part of this site. It should be real easy for you to move on too.

Re: yenko guage question
 

Wait, so I didn't answer you in less than a day and because of that I was not willing to help? Give me a break. I have now decided not to help because you are being rude to other members and I. I do not have a repair schematic for a 990 transmittion but I can tell you the one you have is wrong. A 990 sender does not use batteries, a EB sender does among other things.

Jason, it's all good. He's probably fixing his 1998 Acura Integra right now anyways...LOL
