Tachometer reading double
Posted: Fri Nov 25, 2016 5:54 pm
Hi
New to the forum.
I have a Mk II tiger with a 'Smiths Motor Accessories' tachometer that reads precisely double the correct reading at all times (I have checked against a hand held meter). It is wired correctly to one end of the ballast resistor, as per the wiring diagram. The body of the tach is earthed to the chassis.
It even says '8 cyl' on the face of the gauge but reads as if it were a 4 cylinder gauge.
Is there any way to adjust the reading? or is this a problem that others have encountered? I would like to sort it out and I am hoping that the wisdom here can help.
Thanks for your thoughts.
