Tachometer not working

[Guest]

I bought a new aftermarket basic tachometer from dime city cycles which has wires for the lights in the gauge and a cable going to engine. When I rev up the motor nothing happens on the gauge. Do I have something connected wrong?

We're gonna need more info. The GSR Hive Mind is nearly omniscient, but it is not yet clairvoyant.

Which tach? They sell several. Is it electronic or mechanical?

If it's mechanical, take the cable off the engine and make sure the little blade-shaped widget inside is turning when the engine is running. Hook up the cable to the engine, then remove the cable from the tach and see if the cable is turning.

Its mechanical. I'll do what you recommended here in a few, I just didn't know how the whole mechanism worked. Thanks
