Following a few recent questions and comments from viewers, here is a beginners guide to how electrics work on a narrowboat. It may also have general relevance to people in campervans, motorhomes, caravans and RVs although there are slight differences but the gist is similar.
When I received a panicked phone call from The Narrowboat Experience, who were stuck half way up the Grand Union canal and just too tired to carry on, of course I had to help. So I jumped into my car, shot off to Whilton Marina and ran down the towpath to find Anna and Kath, and give them the benefit of my extensive canal and locking experience and wisdom. This is the record of the day.
