Radio
From the 1943 United Motors War-Time Service Handbook
Auto radio service a mechanic can do without test equipment, for dead, weak or noisy sets. It covers the battery and fuse, freeing or replacing the vibrator, finding tubes with open heaters in glass and metal types, motor interference from condensers, bonding straps and the distributor rotor, front wheel static collectors, and aerial ground and continuity tests, before sending the set to a radio shop.
