My electronic ear muffs have stopped working on one side. I am hoping to fix it up and need some advice.
1. Have disconnected the speaker that no sound comes out of. Now what, how do you test speakers? When I connect an AA battery it does the crackle noise thing.
I guess I could swap this speaker over to the wiring on the other side as it is a known working circuit.
2. If it is the mic that is not sending signal to the circuit board, how do I test a mic?
3. If it is not either the mic or speaker, I might just connect the speakers from the broken side into the good side. What are the risks here? Will adding another speaker increase current draw and have the potential to fry the circuit?
Also, if I do this it really does not fix the problem. I will have sound into both speakers, but only pickup from the one mic. So the bi-directional sound will not be true.
