Hey everyone, new here with my first bike i picked up as a project. My headlight comes on when cranking pedals and i know some things are working, but i believe my coil may be open/shorted? I'm reading 3.4k ohms from just the external coil and 5.4k ohms from just the spark wire. Does that sound right or is something wrong? Visual inspection I'm not able to see a spark when the plug is out and the pedals are cranking. Thanks in advance.
