Thanks all for the replies, interesting stuff.
Jambaugh, too complicated for my knowledge, you lost me with the formulas...no worries. I like the anology to mechanical things, that helped alot.

wow Jambaugh that was in depth explanation.
I thought I 'd attach a picture of what the pieces look like.
Is that black band on the capacitor the negative side?
Thaks for letting me know that the resistor's reading is fine...scared me abit.
if the cap is producing a/c and the...
Was looking for a better understanding of what the componets are actually doing.
I think you covereed that thanks, but have a few more.
Does the fact that the resistor is reading slightly more resistance (3.6 KOhms instead of 3.3 Kohms) mean that the tach
will be reading slightly slower...
newbie needs help understanding a tachometer's "monitor"
Ok let's start with what I have.
I have a 1960s era Stewart-Warner 970 series tachometer in my 1969 Mach 1.
It uses an "ignition monitor" model number 990B.
The monitor has a terminal for a lead that goes to the negative...
