QUESTION: Sorry. 1979 MGB LE.
ANSWER: Hi Robert,
Most of those items are powered off of the green wires on the #6 pin in the fuse panel so that is a good place to start. Use a test light to check for power with the key on and use your wiring diagram to probe for power on the many branches of the green wires.
If you don't have a diagram you can go to my web site and copy one.

QUESTION: Replaced the fuse. It all worked for about :30 minutes. I was driving with the lights on and also with the radio playing. It blew again. Could it be a wire shorting out the fuse? Is this common or do I need to take it to a specialist?
AnswerRobert, it is not common for the same fuse to blow unless you put in a low amp fuse and that line has a lot of items on it. If it is burning a 35 amp fuse then you still have a problem. Which can be an intermittent short. A short in wiring that only happens randomly at times is the most difficult to find because it needs to be shorted out when testing to be able to locate a short.
