Onan engine. Which engine do you have? B48G, or the P220G? Points and condenser, or electronic ignition?

I hsve the P220G not sure about the points and condenser
Expert:  Curtis B. replied 1 year ago.

See link above. No points, electronic ignition. Only part that seems to affect the spark by turning key on and off would be the igniter , next to the crank sensor.

I do see a condenser, I would replace it before biting the bullet for a new igniter .
