Hi, can anyone tell me how to check the switch box, coil packs and stator to see why I don't have spark on 1976 mercury 850 Serial # 4424814. Does anyone know of the website that shows all the dva voltages, troubleshooting and diagrams for mercurys, I can not remember for the life of me. Appreciate any help, Thank you

CDIElectronics.com should have a troubleshooting procedure. That motor is ADI, or does it have a dissy?
