Sort of depends on what the control-data circuit wiring was shorted TO external to the ELT --for example like a 32 vdc bus bar or any power circuit or sneak circuit.
remotely drop a piece of 12 gage or smaller wire across your 12 volt car battery AFTER clearing the area . .
Why would a control-bus carry a high current? This would be a major safety issue. I cannot believe anybody would do that.
