Just seen the above, can't believe it's still untouched ...
my statment stands as written
Your "statment" (sic
) is still completely, totally, utterly wrong.
In constructing the above and your previous post, the bit you've missed (at least I hope you just didn't know it, one would hate to think you ignored inconvenient facts to 'prove' a point ...) is Lucas
was using "14/32" wire lo-on-ng before they ever fitted any fuse to any motorcycle harness.
You have development events in the wrong chronological order and have extrapolated from the wrong one:-
never fitted a 20A continuous fuse to any motorcycle harness it supplied to North America. The fuse you have experienced is likely a Littelfuse supplied by North American-based British motorcycle importers to their dealers to save importing the late
fitted, rated 17.5A continuous.
. The earlier
first supplied/fitted (as models/versions (earliest I know of is '64 Triumph 6T Thunderbird) and/or makers converted to 12V?) was only rated 12.5A continuous/25A blow.
. The only reason Lucas
uprated from 12.5A to 17.5A was expediency - as more electrical gadgets were added, 12.5A could be exceeded relatively easily, bringing a bike to an immediate halt when it blew;
there wasn't (still isn't) a fuse of that type between 12.5A and 17.5A continuous.
a stock harness will pull those loads
Made of Lucas
14/32 wire, I know for a fact they won't, at least not for any sensible length of time.
With advance apologies to most readers here, it's unlikely any Norton
owner who hasn't ever owned a triple, with Lucas
Rita EI switching three '12V' coils, would encounter 14/32's wire's actual current capacity limit. Given you don't have any experience of triples, never mind the other two, you couldn't possibly have any first-hand experience to counteract your theorising in your posts.
The only other possible way another non-triple-owning Norton
have encountered 14/32 wire's actual current capacity is a Commando
with a RM21 alternator run continuously at 6,000 rpm-plus for probably at least twenty minutes (any takers?
To be clear, reason I stress "might" in the previous sentence is, while Lucas
rated the RM21 for 10.5A @ 5,000 rpm - which 14/32 can just about take without showing distress - I've seen some Commando
publicity stating "11A @ 6,000 rpm". My first-hand experience - of a couple of triple short-circuit racers using Rita with three 12V coils - is 14/32 then shows distress inside twenty minutes ... I've previously posted the joke, "Brown/Blue turns brown/crispy" ...
This Board's moderator being "Dynodave", given his experience with Rita EI, his attention drawn to "Rita EI switching three '12V' coils" might remind him of his own first-hand experience; hopefully then some correction finally might be applied to the tosh in your posts ...
you do not understand the fundamentals of a wire gauge capacity
Wrong again. But it's irrelevant. You have simply extrapolated your theories from the wrong reality.
You can pull 20 amps through
14 awg gauge wire
Well, yes, but what has that got to do with anything here?
The "14" in "14/32" is the number of strands
, it's the "32" that's the gauge - SWG ((British) Standard Wire Gauge) - equivalent to between 29AWG and 30AWG. The total conductor cross-section area is about the same as 19
has a cross-section area a gnat's over 2 mm2
, it's bigger than "28/32" that Lucas
rated for 15A; Europe rates modern 2 mm2
stranded for 25A inside 'thinwall' insulation and 17.5A inside 'normal' PVC.
