"Will grounding the coil wire from the cap to the engine (not from the coil to engine correct?) damage my ignition system?"

The path for electrons is from coil to center of cap to rotor, then to individual spark plug wires. Remove the coil wire from the cap, then position it (not with hand) close to ground. You could also do this with number 1 spark plug wire, but then you'd have to be sure #1 is ready to fire. With the method I described, #1 or #4 can fire using the same timing mark.

When checking spark, always make sure the electrons have a place to go, either directly to ground or by jumping a gap to ground. Otherwise, damage can occur to the electronic spark box.
