What’s up fellas, got a 51 I’m working on and I have no spark. Fuel pump comes on all electrical comes on but no spark. I tested……. I have 12v at the cdi. Ground is grounded. I have only 1v going to ignition coils. The blue black and blue yellow is supposed to be a input and I have nothing on those wires! Is my ecu not powering? Where do the blue black and black yellow get it’s voltage before the ecu? All my relays are working. Kick stand jumped tilt jumped neutral safety jumped. I’m down to the ecu and cdi. What do I test to confirm fault or lose of voltage ? HELP NEEDED
