Compared to a modern car the MGB electrics are simple, but due to age, insulation may be worn in places and connectors may not connect due to corrosion. Old style cartridge fuses can also appear sound..... but not connect. Get a good clear circuit diagram or Haynes manual and work systematically through the circuits with a good tester. Or find a good "old school" auto electrician.
