First, make sure the switch tab is not stuck closed. It should flip freely up and down.

If not stuck, then check the circuit for a ground somewhere between the speaker and switch. Also check the switch to make sure current does not flow through at rest. I don't recall if there is an inspection port at the switch. If not, you can pull off the bottom wing root fairing and check at the connections. There should be two bundles of wires there, one for the nav/strobe and one for the stall switch. The nav/strobe will have 3 or 4 wires and probably be a molex or similar, while the stall switch will have 2 wires and probably has a knife edge connector or similar. Put a multimeter on the stall switch or connections and verify current does not flow.
