Work boat battery connection

[Tamar]

A work boat I was on the other day had the normal 1-2-both battery switch and two batteries. The battery positive were connected to each other, am I missing something?, I've never seen this.

For some reason I was recollecting owning a MG-B GT and looked the marque up in Wikipedia. There it is mentioned that early models had positive-earth electrics. It is only a matter of convention and back before LEDs, for instance, lighting would not have noticed...

Some early MGB-GT had 2 x 6v batteries in series

Didn't some early MGBs have acetylene lights?

Might have done, but I recall that it was optional for the Fella walking in front to carry a Lantern along with the flag {#

This was negative earth. Just a strap across the + poles.

You could use a 1B2 switch for two loads instead of two batteries?
Or just as an isolator 'because it was handy' or because it's more reliable than some of the cheap nasty types with the red key. Or they didn't want someone nicking the key.... Or it filled the hole in the panel nicely?

I once wired up both ends of a 2 throw switch to make sure I couldn't switch it the wrong way so convenience might well be the answer. I'd certainly agree that if the switch was already there I'd leave it as it's neater and just wire it up to avoid mistakes.
