Which fuse board diagram is correct ?

YES!!!
Also safe to do with a 24v battery.
Why do you think that the Yanks have 110v mains - you don't get so much of a belt from their mains as we do from ours. We are masochists here, we like the extra thump as it hits us.

As in, you cannot get a shock off 12 volts, 90 volts is the point at which you can start to feel a very slight shock.

Actually, are you saying it's safe to touch both terminals of a 12V lead acid battery at the same time?

Yes it is, BUT you must never forget the massive fire potential bottled up in that black box. It has enough energy stored in there to turn your engine over for a fair while so imagine what it can do to wiring that has shorted without a fuse to rupture and interupt the current, or a heavy load fused larger than the cable is sized to take.

The higher voltage means smaller cable sizes for a given amount of power.
The yanks are pussies anyway

That's something learned then. I've always been extremely careful around vehicle batteries, with wiring and particularly when wielding metal tools near them (wielding, not welding ), and I've always assumed there would be dire consequences if I somehow shorted the terminals with bits of me. I've had one or two 240VAC shocks - yes, quite stimulating!

Indeed; drop a spanner across the terminals and you'd bluddy know about it!!

Handy trick if you have a shorted cell and can shake some sulphate loose also!
