Do you have diode test function on your DMM?  if so, you can inspect 
each diode in a bridge in circuit, or at worst take off one lead from 
Plus (+) bus.  Silicon diodes will show 600 mv across each one, 
germanium 300 mv.  Make sure the capacitor following the bridge is 
discharged before testing, and radio is unplugged from everything.
