Default Smith's Tach settings
Just curious as I may have messed up my Smith's Tach settings as I was messing about under the dash.

My Smith's tach has a 8-6-4 cyl rotary switch on the back. If the switch was disturbed and moved to the 4 cyl setting, would my V8 appear to be running at twice its RPM:

Example: the V8 is running at 1000 RPM but the tach says 2000 RPM.

Can anyone help?

Cheers
Greg
