    A test with an ohm meter on the coil secondary should tell the coil health. Not sure what the actual reading would be on an A50 coil but I would assume from testing many Johnson coils that the value would be 3000 to 8000 ohms.

    Johnson coils unless physically damaged have withstood the test of time and are almost always good.
