any help with basic 12v set up please

[prv]

Why??? What kind of school did you go to that taught 12v electrics?

Um, any school. Electricity (batteries, switches, lightbulbs, etc) comes into science lessons at quite an early age. Perhaps not enough to safely rewire a boat (volt-drop and current-carrying capacity of a wire probably don't come in till GCSE Physics at a guess, and some people won't grasp it anyway) but certainly enough to answer the OP's question about how to wire a switch into a circuit.

Errrrmmmm... not at my school it didn't - shame really - would have had to be more fun that cutting up frogs.....!

I'll be entirely honest - I did my schooling up to '77 - never did any of that stuff - found the responses here very useful... just a view from the great uneducated you understand...

So your syllabus included biology but not physics? Seems very strange to me, but what do I know, I wasn't born then

Mind you, I think my mum's education may have been similar; she went to a convent school which was of the opinion that "girls don't need to know such things".

you've ALL been most helpful. thanks.

will look for a busbar and wire it up later in the week. the little cabin boat of a friend is being slowly restored and now wants a little bit of power as just had fitted a small fourstroke outboard with 6amp alternator
