Electrical woes

Q: I have a 1976 Triumph Bonneville that I built into a bobber. The bike ran great before I stripped it down and rebuilt it. I ran my own simplified electrical wiring harness. It already had the electronic ignition system installed. I didn’t touch the engine. Now I do not get spark when I kick it over. The battery shows 13.5 volts, the resistance is good on both coils, and I have checked all the wiring for continuity and correct connection. When I turn the key on and off, I get spark at both plugs. I also installed a new key ignition switch. What’s wrong? — Perry/via email
