Hi Guys.

Working on a late 72 RV125.

Issue: the 3 position key ignition switch does not shut bike down or keep it from starting.

All 9 pins I checked with a multimeter and have continuity, switch seems good.

Bad ground?

Looks like your bike shuts the magneto ignition off by grounding it to the switch housing.
If you've done something like powder coat the frame, then you have eliminated the switch ground.
