Tachometer question

Hey Rod,

Just reading your post and have a few thoughts about it.

The first and most obvious to me is that the tach is not calibrated properly. Correct me if I'm wrong guys but the tach is a meter...no signal ,no pointer deflection. If it is already registering 2k with no signal, it is not calibrated to zero. If the tach shows zero when it is not hooked up, and goes to 2k after hooking it up but without starting the engine, it is getting a partial signal from somewhere else in the circuit.
