I have an old school dwell meter. How do I hook it up?BTW, you can also use your Engine Analyzer "dwell" meter in the 4-cyl mode to do another sanity check. That is if you have one.
And the dwell meter will give you the Mercedes definition duty cycle (because it measures the percent time the points are closed for the old style adjustable mechanical points, which is similar to the amount of time the diagnostic port signal is zero from the X11 - mercedes definition)
Same? Black on #2, Green (fr dwell meter) on #3.
