Yamaha ty175
Just had full engine rebuild but can't get it to spark.
Coil / plug works as tried on another bike and has seperate earth wire from coil to engine, so it's got good earth.
Points open, condensor is new.
Flywheel is magnetic, new woodruff key
How can I test generator/ ignition coil.
When I use multimeter from black wire to earth I get 1.6ohms . Getting same on a spare unknown ty windings.
