I just aquired a Sunpro by actron Inductive Engine Analyzer with no
manual...
I want to get RPM readings and a little picture on the back of the
instrument shows the Inductive pickup going to a spark plug wire and the
black wire on ground and the red wire on the negative side of a coil. Now
the coil it shows looks like the coil I used to see on my parents 1978
Dodge Monoca Station Wagon. I want to hook it up on a 86 Buick Regal with
a 307 on a HEI ignition system. Where do I hook up the red lead on the
Buick? Thanks for any help.
