IF your replacement coil did not work (crossed fingers), then do a quick resistance check on the wire going from the igniter box to that coil. Should be a blue/Yellow wire.
Unplug it at both ends, then check to ground; should be OL or Open Circuit. If it is anything else you have a suspected short in the wire, and your signal is just going to ground rather than operating the coil. Next check from end to end of the wire. It should be a very low resistance, a couple ohms max. If not, you have a corroded contact somewhere that needs cleaning up. If it reads OL or Open you have a broken wire or contact, and need to trace it down to find the break in the wire. Hope that helps! I'm not at home or with my bike, so I'm going off http://www.geocities.ws/fantonino/Tech/schematics/cb750.jpg for the wire colors. -Kurt On Sat, Dec 12, 2015 at 3:50 PM, 'Ross M.
