Just bought a new ride. 1972 Convertible which was running great. Had purchased a Sears Engine Analyzer months ago at a garage sale. Hey I have a great idea lets see if this thing works. Worked fine. I didn't get beat for the $10. Unclipped the coil lead and a wire broke at the coil. Negative side. Spliced in less than 3 inches of wire put a new end on it and hooked it back up. Ran for two seconds and stalled. For two days now it just cranks. No Start. Cleaned and reset the points. Removed cleaned coil and the leads. Still just cranks. What am I missing? Car has a after market hood tach. (Doesn't and didn't work before) Fuse, Fusible-link, Wiring Diagram for a coil? Trouble shooting flow chart? Thanks for looking and thanks in advance for any help.
