Hi Carl.
If you have a multimeter try doing a continuity test on the audio wire. The JM2-U are old mic's and the wire could be broken due to age/use. Also ensure that the battery terminals are free from corrosion.

Never, ever, ever....bloody anything ever!
Far too many radio's to list here. But I do own a legal one...

Test the cartridge with a digital multimeter set to AC millivolts, whistle into the cartridge, id expect 50mv or more.
