thanks. i saw it up there on my car too. but reaching it, let alone removing and attaching wires looks to be quite difficult as laying on the floor my arms are simply not long enough to even reach anything up there. could they have made it any more inaccessible? i'm thinking maybe it would be simpler to run a new wire from the ignition switch to the coil.

BTW, am i correct in thinking it's just a bit of ceramic inline with the ignition wire that when cold creates little resistance but heats up when 6v starts coursing through it and when it heats it becomes slightly more resistant and reduces the voltage to the coil thus putting less stress on it and the points. ...or something along those lines?
