spark and no spark

Found some of loss, and double check what I did yesterday because I forgot about the on/off switch.

Meter reading as follows;

Battery + post to starter bolt=1.2

Battery + post to wire post clamp=.000
Battery + post to top post/clamp of on/off switch=.09
Battery + post to bottom post of on/off switch=.569

bottom post of on/off switch to starter bolt=.601

Also, check the ground again a .611 this time.

Should I get some more cable and run a negative from battery to engine block just to eliminate that question?
