Welcome to the forum!

Connections corrode and during periods of disuse lose continuity. The first thing to do is unlpug all the connectors, spray them with electrical contact cleaner or dip the in acetic acid (white vinegar) (if you acid clean them, rinse with clear water and dry the water with denatured alcohol) then lube the connectors with dielectric grease.

The ignition system does not need the battery for spark, the battery is just for running the lights and electric starter. If you just unplug the key switch and jump the solenoid, it should have spark if the wiring has good connections.

Don't forget to clean the ground connection points when cleaning the connector plugs.
