I did not work on the cars, but I did hook our 73 Mustang Convertible, with its 302 2v engine, up to a refurbished Sun Oscilloscope just to see how well the scope was working after over 50 years. The refurbish work was done nicely by a former Sun rep, who works in conjunction with a group of other former Sun reps across the country. I had a blast tinkering with it. So much so that I plan to do it again this afternoon, just because it is a nice day and I feel like tinkering with it again!
Lynda and I did make a quick video showing my first time tinkering with the refurbished Sun scope. It is not meant to be an instructive video session, as in how to use the scope. I really put it together to show Dave Wager, who performed the refurbishment of the scope, how well it turned out after he had it delivered to us in Upstate New York. After I replace the ignition points I will do a video on how these scopes are used to set the engine tune variables to specification. That woulds like a fun weekend project to do, actually. I pulled a plug out the other week, and the electrodes on the plug I pulled looks great,. The scope patterns I saws do not indicate I am having a problem with the plugs with the voltage required to fire them, and the dissipation pattern of post-arc secondary current activity do not indicate a problem with the plugs or any other part of the secondary ignition either. So, I will not be replacing the spark plugs, just the points because the 10 degrees from spec in dwell, which tells me it is possible the rubbing block has work down more than I like, and doing a points gap reset with used points is not as accurate in attaining a good correlating dwell angle measurement as compared to setting a gap using a new set of points with no arcing on their surfaces.
