Only way to make the ELT inert is to pull the battery pack out.
Artex uses ship power for the light in the cockpit, not sure about Honeywell.
There should be no direct, or even indirect, path between the ship power and the ELT battery pack.
Looking at an Artex pack, I can see a potential failure mode that would short a cell out. I have no reason to think Honeywell's execution of a battery pack would be much different.
If I'm thinking what the AAIB is thinking, were all gonna be pulling ELT's out of everything.
ETA: Self Loading Freight. on the Artex battery pack, it goes straight two 2 fuses in the pack itself.
