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

Customer: replied 11 months ago.
I hsve the P220G not sure about the points and condenser

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 .
