Radio Connection

[stacks]

I convered my car to 6 Volt NEGATIVE Ground.  I had to switch the wires going to the Amp Guage, and the wires going to the coil.  Everything seems to be working ok now, but I am not sure that the radio can operate with this configuration.  It appears to me that I would have to isolate the radio and run a positive wire to the case of the radio and a ground to the electrical connection.  Is that correct?

If the radio is still original, it will work fine on either negative or positive ground - it doesn't care. If the vibrator in the radio was replaced with a solidstate replacement, then you would need to replace it with a solidstate one which is negative ground but as long as  it still has the original type vibrator in it, it doesn't matter whether is neg or pos ground, it will work fine.
