tachometer

Wrench 
Hi,
I have a little problem with my tachometer .....
At idle, it tells me 2000 t / min, can you adjust the rev counter?
Where should I connect the tachometer?
Thank you for your help

Is this the factory or an aftermarket tach?

If it is the stock tach it should be connected to the + side of the coil. If using a MSD ignition you can take the output off the Tach line however you need to get a tach adaptor from MSD (Part #8920) to work properly. If you have the RCCI converted tach you can take the signal directly from the MSD box. Need more specific info on your setup to know for sure. I am not aware of any adjustment take can be made, maybe someone else can answer that question.

No, the rev counter cannot be adjusted. It needs to be in-line from the ignition to the coil with no other lines attached to the + side of the coil.

Let me check your shorts!
