mine doesnt do anything special when I hit the button either but I know its connected as there is a miss when I push the button half way. I think my capacitor (storage component) is toast. The only thing I see on a VOM is about 4.5V to coil and about 9V to the coil when the ignition is "on". I know the VOM is the wrong tool but I have yet to get my O-scope on it, fearing potentially 300V will blow something in the scope. Its not that important to me unless a scope guy can tell me differently. My leads are cheap, 2GHz rated, no max voltage given.
