Autometer tacho install

Anonymous · Post by **Anonymous** » Thu Jun 16, 05 9:23 pm

Hi all, does anyone have a tacho wiring diagram?
I have left it in the garage now, but I am sure it has 4 wires.
a black/red/white and a green? it has the shift light built in.
Also the car is a charger, any sugestions on where to fit it? the dash top is pretty good and only has one small crack.
Thanks
Morgan

White wire = dash lighting

Red wire = 12v

Black wire = ground

Green wire = -ve of coil or the tach output from your MDs and the like.

You the man Dave, thanks for that, a few thing have got me down today.
Hopefully once I have got most of these dials sorted, and the valve body it will start!

Hi

I have just been wiring a tacho in my Coronet (to replace the clock that doesn't work).

The problem I have is that when I turn the car off the needle rests at 1000 rpm rather than at zero. But if I then turn to ign then off it resets to zero like it should.

Followed instructions correctly from box (which were the same as above) - any ideas?

Thanks

Martin

I think you will find that is normal mine shows the last rpm before ignition was cut

People often look at my tach and assume it is damaged because it will point to anything from 1000-1500 rpm when I switch the engine off.

Completely normal.

I remember it mentioned it in the Autometer fitting instructions I had?

mine stops anywhere between 1000 to 1500 also, an it does say that is normal in the manual
