Vintage Sun Super tach II wiring question
Permalink  

Guys,

 

A while back I got a great vintage Sun Super Tach II (Blueline) from 427Carl. I'm ready to use it now, but the wiring makes no sense.

I've been across the web and can't find any illustration or description matching this one.

 

Wire colours appear as such;

Green

Grey

Black

Black

Black/White Stripe

Black/white Stripe

 

I understand the green is generally the signal off the coil negative.

The others...perhaps the Black/white is lighting...no clue other than that.

 

Any help or reference appreciated.

 

Cheers, Mark

Not sure if it helps any and you may already know this but GM used grey for dash lighting all through the 60's at least.

Assuming green is signal, would it hurt anything to probe around on the others with 12 volts just to see.

I could temporarily hook it up underhood with test leads to the running GP to see what I get.

Would it fry it if the negative took 12v positive hit?

Hmm, that's scary!

Have you opened it up to see where the wires go inside? That may give some clues?

Strange colouring..maybe the wires have been joined internally. Usually green, red black and white....maybe you have one that has an external shift light option?

Try a 9v battery , that's what I did with mine, it was enough to move the needle for my tell tale, and light it up, also turned on my shift light, just a suggestion, if it has any of these, then process of elimination after that perhaps

I think this Super Tach II is a mid to late 70's model. Still looking and have found zero on this wiring. Could it have been modified for some electronic system in the past?

I might try to mock it up on my 67 ( probably at the risk of frying it ), or open it up. I'll need to pry off the plastic chrome bezel to get the works out. There are two small recessed nuts on the back that will allow the works out with the bezel off and glass removed. To me both seem equally risky.

So close...

Yah ... can you not see the back of the tach? If in a cup, easily remove the cuP?

Well, if anyone else ever encounters this somewhat unusual wiring configuration....

 

Green = Tach signal from coil negative.

Grey = 12v Power

Black x 2 = Grounds

Black/White trace x 2 = Lighting

 

Actually, it was really the grey that was unusual.

Cheers,
