full thottle switch - how ammeters work

[tomc at satx.rr.com (tomc)]

Hi all,

I just caught up with my reading. Patrick (and the list) you can not
measure dwell with a volt/ohm meter. You could with an o'scope though.
What you are actually measuring is a pulse width, which shows how long
the signal to fire the plugs stays on and off. RPM is very closely
related but you are counting the pulses instead. Usually why you find a
rpm and dwell measurements on one cheap instrument.


Hope that helps,

I am sorry if my email offended, it was not ment that way.

well I have ordered a new multimeter that will do Dwell, so that will
solve
the problem, but now I am confused, if dwell is not mA nor mV , then why
everyone talks about a mA reading on the test lead or am I so dense that
I
am mixing up things together and doing a process of self confusion and
in
annoyance by everyone with my dumb ass questions..
