 |
|
I bought one of those tachometers you put on the dashboard. I tested it in the engine bay first. So needle does not go up very fast nor does it come back down fast either. I've never seen a tach on a vw before. but is that normal cuz the engine is a slow one or am i missing something?

A cheap generic tachometer is Unlikely to read correctly. Better hook up a good tachometer/dwell meter at the same time and compare the 2 tachometers.

Clock and fuel gauge housing is 85mm, and with bezel the face is about 90mm, Cheers. |

| to answer your original question most generic tachs are set up to run a 4,6, 0r 8 cylinder motor if the needle is very erratic check for a switch to adjust this setting. I have heard of people putting the Jiggler/vibrator like on the gas guage to accomplish a cleaner needle movement but have not tried this. the green wire on most generic tachs goes to the same point on your coil as your condensor. and there is a seperate power wire (red) as well. I have never seen one I could not get to work smoothly . Sun makes a tach the same size as the clock in most type 3 and I did the same to mine. Although Gizmobobs looks a whole lot more stock than mine. I will post a link to my phot bucket once I verify I have that pic up |

I ran a long wire from the dash, along the tunnel (under the carpet) and out through the grommet under the rear seat in the battery compartment, and back into the engine bay...

Without the FI, I've been thinking of running the wire through the extra fuel line since I've got the pan off. |

Recall seeing a post about using the unused red wire in the loom that is not used in manual trans models.
I know that my square has it in the engine wiring and in the wiring under the dash.

Yup, that's what I used on my 71 Square-vert.

I've just up-graded mine with a tachometer which looks "at home" in my dash...
It's a vintage Smiths (made in UK) vintage 70's something tach. it's a perfect fit into the clock opening.
With a redline that you can setup wherever you like
