I know this thread is old but I have a 88 big bear no spark, replaced stator and coils regained spark took for long ride then lost spark again all resistance and voltage tests good Iv replaced regulator, ignition coil, plug cap, plug, ignition, tested killswitch and neutral switch still no spark, only getting 3 volts to orange wire from cdi to coil so replaced cdi and it was still the same any ideas?
