Hi,

The tacho gauge inserted onto a video show the correct value as a number, but the needle does not move, and is pinned to the right. Both for speed and RPM. Thoughts? Thanks!

Sounds as if it is not scaled correctly.
Does 'Pinned to the Right' mean full deflection or '0'...? Some tachometers read anti-clockwise...
